My bad, rpm -V glibc returns nothing.

I just caught up on the thread.  It looks like the core issue was never 
actually resolved:  "getent hosts localhost" still doesn't return the 
expected result, right?


    $ getent hosts localhost
    ::1 localhost localhost.localdomain localhost6 
localhost6.localdomain6

    $ grep ^hosts /etc/nsswitch.conf
    hosts:  files dns myhostname

If you're not getting the expected result from "getent", and if your 
nsswitch.conf lists "files", then glibc is somehow broken.  "rpm -V 
glibc" might tell you how, or it might not.  Could be that glibc can't 
load /lib64/libnss_files.so.2.


In any case, DNS is now providing you with a result for "localhost", and 
that'll work around most of the problems, but you really should take 
steps to fix glibc.  With something that low-level broken, I'd urge you 
to build a new system from scratch, and automate the build with some 
configuration management tool this time, so that the next time you need 
to rebuild, you can do it quickly.

Added back the IPV6 to /etc/hosts a couple days ago for grins and giggles.
No longer getting IPV6 errors in logwatch for bind. Everything working.

I think removing my ISP's nameservers from /etc/resolv.conf was the fix.
They have been in there forever so still have my fingers crossed.

Again, many thanks!!

The mail in question is system mail sent via cron. I access it from both
inside the network and outside. Due to being on a dynamic ip, I can't send
mail to the outside but I can receive it.

As I indicated earlier, removing those lines from your postfix config
will have no impact on your ability to reach your roundcube instance.

Unlike the windowz world, you mostly don't need to "reboot" a machine
after making changes to a service (e.g., your postfix config change).
An unnecessary reboot can bring in many issues so makes debugging a
problem difficult. Instead, restart the service in question (often a
reload is all that's needed, but a service restart generally doesn't
hurt in a single/lower user environment).

Unless you are VPN-ing (or equiv) my sense is that you are currently
getting to your mail (roundcube) from outside your network. Earlier,
when it wasn't working, my sense was that you were inside. If that's
true you can't really tell if your issue has been resolved as you are
coming at things from different network directions.

Pretty sure SELinux is turned off unless it got turned on without my
knowledge through an updtate/upgrade.

I removed the TLS lines from main.cf I added last night and remotely did a
reboot from here at work.

Mail is again working!! I am skeptical to mark this thread solved as I
thought it was solved back in July.

I think, removing my ISP's DNS servers from resolve.conf was the fix, could
be removing IPV6 from etc/hosts. Might put it back in just to see.

Again, many, many thanks!!

I really want to thank everyone for their help and patience!!

Since the localhost4 approach worked, commend out the ipv6
localhost entries in your /etc/hosts file, then try:


IP6 is commented out


 dig @localhost localhost a


That works


again. If that works try:

 telnet localhost 143


This also works


once again. If those work, it would seem that your ipv6 is messed
up and your system is trying it first and not falling back to ipv4.

Regarding your nameserver list in /etc/resolv.conf. If you have a
working 127.0.0.1 nameserver you generally don't include external
nameservers in that list. So, if non-ipv6 things seem to work, I'd
remove the two non-127 nameservers from that list.


Removed the two nameservers. Still can't access mail. Getting
connection to storage server failed on the roundcube login page.




That you can now successfully get to "localhost" is good progress.
Seems you want to stay away from ipv6 networking issues unless/until
you resolve whatever that issue is.

Roundcube is, potentially, a totally separate issue. I don't use it,
so can only suggest minimal debugging ideas.

What is the hostname that you use to get to your roundcube instance?
Can you resolve that:

dig  a

If you get an answer, is the ipnumber correct?

Note, if the hostname for your roundcube instance is one of the ipv6
entries in your /etc/hosts file, I'd remove that - and either put in
an ipv4 entry or put an entry for it in your dns.



Thanks again! I still think it's a mail issue. I can't get mail using
usermin either.

Think I'm going to remove the TLS stuff from postfix main.cf that I added
yesterday and retry.


If I missed this further up thread my apologies - is SELinux enabled and

Those TLS lines that you added to your postfix config file yesterday
have nothing to do with your ability (or not) to get to your
roundcube instance. I believe that the roundcube frontend is an
application that runs via httpd/apache. Assuming I am correct on
that, debugging your apache setup would be the next set of things to
look at. Confirm that it (apache) is running and listening on the
port(s) you expect it on (netstat and ps will help there) and then
start with the access and error logs.

Thanks again! I still think it's a mail issue. I can't get mail using
usermin either. 

Think I'm going to remove the TLS stuff from postfix main.cf that I added
yesterday and retry.

That you can now successfully get to "localhost" is good progress.
Seems you want to stay away from ipv6 networking issues unless/until
you resolve whatever that issue is.

Roundcube is, potentially, a totally separate issue. I don't use it,
so can only suggest minimal debugging ideas.

What is the hostname that you use to get to your roundcube instance?
Can you resolve that:

   dig  a

If you get an answer, is the ipnumber correct?

Note, if the hostname for your roundcube instance is one of the ipv6
entries in your /etc/hosts file, I'd remove that - and either put in
an ipv4 entry or put an entry for it in your dns.

The first two nameservers belong to my ISP. Should I move 127.0.0.1 to the

Randomly adding lines to a config file isn't going to help things.
Those lines, which you added to the postfix config (which will have
no impact on dovecot), are -- as the RH documentation indicates -- to
turn off weak protocols, they don't turn anything on, other
directives are used for that.

In your pastebin:
  
  

you show three nameservers:

  nameserver 166.102.165.13
  nameserver 207.91.5.20
  nameserver 127.0.0.1

I can't tell if that's what you still have in place, but note that
your dns queries will query those DNS servers in that order. Based on
that order, the "localhost" (127.0.0.1) server is the last one that
will be queried. Unless explicitly queried (e.g., with an
@ syntax) it will only be queried if the other two fail.

Could you confirm the current order (and perhaps list) the
nameservers in your /etc/resolv.conf file - so we are aware of any
changes.

I did a "localhost" query against the first two and they respond
correctly, e.g., 

  ;; QUESTION SECTION:
  ;localhost.   IN  A

  ;; ANSWER SECTION:
  localhost.86400   IN  A   127.0.0.1

  ;; Query time: 100 msec
  ;; SERVER: 166.102.165.13#53(166.102.165.13)

Somewhat related to the:

  > telnet localhost 143
  > 
  > fails [while it works when you try 127.0.0.1]

In an earlier message (from Sunday, August 26, 2018 14:37:57) you
state:

  > I have all the files shipped with CentOS. I created 2 zone files

could you please enumerate the "named.*" files that you have under
your defined directory. Note, if you've chrooted named that's a
different location than in a non-chrooted setup.

Then there's this:

  > ; <<>> DiG 9.9.4-RedHat-9.9.4-61.el7 <<>> @localhost localhost
  >+short
  > ; (1 server found)
  > ;; global options: +cmd

do you *really* have a name server running on your local machine?
Just thought I'd ask. 

While you are at it, could you show the current state of your
/etc/hosts file (as well as its ownerships and permissions).

Yes, that is correct localhost fails but 127.0.0.1 responds.

Can we guess that you don't offer TLS for IMAP connections?


That must be successful first. You can too test "lsof -i :143" or "ss

Running lsof -i :143, I get:

So port 143 is listening. Are we back to the point that your DNS or NSS 
is broken so that even


telnet localhost 143

fails while

telnet 127.0.0.1 143

is successful?

I have all the files shipped with CentOS. I created 2 zone files, domain and 
reverse from the example in RHEL Documentation 
https://access.redhat.com/documentation/en-us/red_hat_enterprise_linux/7/html/networking_guide/sec-BIND#example-bind-zone-examples-basic
 

https://paste.fedoraproject.org/paste/9-ZvmUg5vF-UI7lfuAIJjQ

I did find one typo in the domain zone but correcting that didn't help

Getent hosts localhost and getent hosts 127.0.0.1 returned no info.

Sorry to say, but you have to learn to analyze problems systematically

get Roundcube involved.


You see a basic error message "Could not connect to localhost:143". So 
test that without using additional software. Foremost consult the 
maillog, in this case the log content produced by dovecot. And test 
connectivity on the lowest level.


echo QUIT | openssl s_client -connect localhost:143 -starttls imap

That must be successful first. You can too test "lsof -i :143" or "ss 
-tulpen | grep 143". And tail your maillog.

That's a secondary issue.  A properly configured DNS server *should* 
answer correctly for "localhost".  Yours doesn't.  It's broken.  Red Hat 
ships ISC Bind with a working configuration (/etc/named.rfc1912.zones).  
I'm not sure whether you're using something else, or if you've removed 
the RFC1912 zones.  Fix that later.


"host" and "dig" are both DNS tools, and won't tell you if your files 
are being used properly.  While you're troubleshooting the libc name 
resolution system, use "getent".  "getent hosts localhost" and "getent 
hosts 127.0.0.1" should return something that looks vaguely like the 
data in /etc/hosts.  You can also verify that it works in practice using 
"telnet localhost 25" to verify that you can reach services running on 
the local system.

Thanks. I did open the port but made no difference.

I found this in the roundcube mail error file:

[26-Aug-2018 11:48:41 -0400]:  IMAP Error: Login failed for tdukes
from 192.168.1.102. Could not connect to localhost:143:

/usr/share/roundcubemail/program/lib/Roundcube/rcube_imap.php on line 197
(POST /?_task=login?_task=login&_action=login)

There is also a warning about the time zone. It's set as America/New_York in
php.ini

Thanks, yes it's a CentOS 7.5.1804. I do not know about the system.

That part of the log just indicates that your service which is called 
inb port 10024 isn't running. In your setup that is likely the 
amavisd-new filter service. Make sure it runs or take it out of your 
Postfix configuration.

I haven't read through all of this, but is this a CentOS 7 machine? If so .. I

My ip has changed since I ran telnet localhost 25 as I rebooted my router.
But it is correctly reporting the IP.

OK in that case something is really taking your system for a ride. I
would check to see if that  71.28.79.87 is your 'public' ip address
with

curl -4 icanhazip.com

if it is then something from named or some other utility is
translating localhost for you.  host -v localhost might give you more
information on what is giving lookups crazy answers

[smooge@linode01 ~]$ host -v localhost
Trying "localhost.members.linode.com"
Trying "localhost.smoogespace.com"

You are multiply defining localhost and localhost.localdomain.  All
there should be is:

   127.0.0.1localhost.localdomain localhost
   ::1  localhost6.localdomain6 localhost6

But that's not the underlying issue, it's just a complication.  What
the 'getent hosts 127.0.0.1' is showing is that the system is either
not retrieving host information from the /etc/hosts file or not
retrieving it all. That same command on my system returns

  127.0.0.1   localhost.localdomain localhost

i.e. the line identical to the one in /etc/hosts.  Yours doesn't. What
does /etc/host.conf contain - does it have the line 'multi on' in it?

Your nsswitch.conf files shows that you are retrieving information from
sssd for users. (But not for hosts, so it's not relevant here)

Are you running your own named?  (I thought you said you were - this

OK.  /etc/hosts isn't being used.  You indicated earlier that you had 
more hostnames in that file.  They should show up there.


Let's go back to pastebin.  What are the contents of /etc/nsswitch.conf 
and /etc/hosts, now?


Are you running nscd, nslcd, or sssd?  If so, you may need to stop them 
or flush their cache.


What do you get if you "dig @localhost localhost +short".  If that 
doesn't return a "localhost" address, then the name server that you're 
running has a broken configuration.


Do you get any output from "echo $HOSTALIASES"?

So are you saying that if you do 'telnet localhost 25' it actually
tries to connect to '71.28.79.87'?

If so, then that seems to indicate that host lookups are still being
done primarily through DNS and it isn't looking in your /etc/hosts
file.

What happens if you do 

  telnet 127.0.0.1 25

what about 

  telnet ::1 25

Can't say that's what I expected.  What about "getent hosts 127.0.0.1"?

Also, uncomment the ::1 line in /etc/hosts.


Can you reach localhost by "normal" means?
     telnet localhost 25

I cannot.



Can you share the specific output of the command?  It might help. From 
what you've told us, localhost resolves to the IPv6 local address, and 
that address is present on your "lo" device.  You *should* be able to 
connect.  The type of error might indicate what is still wrong with the 
system.

A bit further up in the roundcube config file there's a line defining
the database connection. The username, password and database name are
all in the definition - something like

 $config['db_dsnw'] = 'mysql://username:password@host/database';

That should be it. Putting dns first works if you can guarentee that
DNS works fine all the time but if your DNS caches that localhost
doesn't exist then /etc/hosts isn't used.

#
# /etc/nsswitch.conf
#
# An example Name Service Switch config file. This file should be
# sorted with the most-used services at the beginning.
#
# The entry '[NOTFOUND=return]' means that the search for an
# entry should stop if the search in the previous entry turned
# up nothing. Note that if the search failed due to some other reason
# (like no NIS server responding) then the search continues with the
# next entry.
#
# Valid entries include:
#
#   nisplus Use NIS+ (NIS version 3)
#   nis Use NIS (NIS version 2), also called YP
#   dns Use DNS (Domain Name Service)
#   files   Use the local files
#   db  Use the local database (.db) files
#   compat  Use NIS on compat mode
#   hesiod  Use Hesiod for user lookups
#   [NOTFOUND=return]   Stop searching if not found so far
#

# To use db, put the "db" in front of "files" for entries you want to be
# looked up first in the databases
#
# Example:
#passwd:db files nisplus nis
#shadow:db files nisplus nis
#group: db files nisplus nis

passwd: files sss
shadow: files sss

I've re-enabled IPV6 but it didn't seem to help.

In the file /etc/nsswitch.conf there is a line that starts hosts: what

Well it's certainly trying to connect via v6 - that's what the ::1 on
that line is.

I think part of the problem is that 'localhost' is being interpreted as
the IPv6 loopback device ::1 and not the v4 127.0.0.1 - it may be that
roundcube has got a wrong mailhost stored. Try running the following
SQL command on your roundcube database:

 mysql --user=rc -p roundcubemail -e "select username,mail_host from users;"

It will prompt for the password. (Obviously use a different user if
it's not 'rc' and a different databasename if it's not 'roundcubemail'
- they are the defaults and are defined in the roundcube config file.)

It will come back with a list of the users defined and the mailhost it
will attempt to connect to for that user.

You have it disabled in the configs you have shown.. but roundcube is
configured to expect it to work. You are going to need to figure out
where that is in the dovecot (possibly a

find /etc -type f -print | xargs grep -l "::1"

might give you some ideas unless this is in the database where you
will be needing to play with that. It may be just easier to just turn

OK. There are a couple of things:

   Aug 23 21:47:18 ts130 postfix/smtpd[3750]: warning: hostname localhost does 
not resolve to address 127.0.0.1
   Aug 23 21:47:18 ts130 postfix/smtpd[3750]: connect from unknown[127.0.0.1]

That needs to be fixed. What does the entry for 127.0.0.1 look like in
/etc/hosts? Have you also defined ::1 to be localhost in /etc/hosts?


   Aug 23 21:47:21 ts130 dovecot: imap-login: Login: user=, 
method=PLAIN, rip=::1, lip=::1, mpid=3754, secured, 
session=<9W1yjiR08AAB>

So you are connecting over TCPv6 from roundcube to dovecot?  Is that
what you want?

What is the IMAP hostname in the roundcube configuration?

It sounds to me like you just have a broken apache httpd or roundcube
setup.  Try ignoring that for now.

Can you verify that mail is getting to where you've got it set up
using other tools, such as mutt or just looking at the spool files?

So, again, what do the dovecot logs say? 

How is roundcube setup? Specifically what is the IMAP server set to?
Remember, if you have changed the server definition in the config, the
individual accounts that were already defined in the database will
still have the old server definition.

Thanks,

I have removed DNS3 from ifcfg-eno1 and set ONBOOT=no in ifcfg-enp1so0, reboot 
and still can't read mail. Logging into roundcube either times out or if I get 
in, the inbox is empty.

You have two physical devices using the same IPv4 subnet.  Disable the 
one you aren't using.  Set ONBOOT=no in 
/etc/sysconfig/network-scripts/ifcfg-enp1s0 or remove the file entirely.

I caught it after I did it, that's the /etc/host.conf

/etc/host should be:

127.0.0.1   localhost localhost.localdomain localhost4
localhost4.localdomain4
192.168.1.110   ts130.palmettodomains.com   ts130

I think the error may be here:

/etc/hosts:
multi on

If that is the /etc/hosts file then something is changing it somewhere
(and the kernel rpms do not touch this file unless someone wrote over
it.) The file should be:

127.0.0.1   localhost localhost.localdomain localhost4 localhost4.localdomain4
::1 localhost localhost.localdomain localhost6 localhost6.localdomain6

The second problem may be in whatever created that ifcfg-eno1 file. I
have resorted and cleaned it up so it is easier to look at

DEVICE=eno1
NAME=eth0
BOOTPROTO=none
BROADCAST=192.168.1.255
DNS1=166.102.165.13
DNS2=207.91.5.20
DNS3=127.0.0.1
GATEWAY=192.168.1.1
IPADDR=192.168.1.110
NETMASK=255.255.255.0
NETWORK=192.168.1.0
DEFROUTE=yes
DOMAIN=palmettodomains.com
IPV4_FAILURE_FATAL=no
IPV6INIT=no
ONBOOT=yes
TYPE=Ethernet
UUID=cfd35a8f-6c40-4a80-bff5-821a91d0775b
ZONE=public

The third problem is possibly your DNS3 which is pointing to 127.0.0.1
which means you have a local nameserver running on the box. No idea
what that is but it is probably something that needs to be
reconfigured or turned off.

Whsh, senior moment!!

Here's the link:
https://paste.fedoraproject.org/paste/MMNEJmqIrEzK-A4N3MR0ZA

I just recently disabled IPV6 due to errors resolving I saw in the logs.
This was AFTER mail quit working the second time. It did not correct the
problem. Both times, this has happened after a kernel upgrade. I have had no
errors this time, except for IPV6 stuff.

TIA

In the URL section of your browser there should be something like
https://paste.fedoraproject.org/paste/GzNwzOQt~uZdK5AahxX4Rg

That is the URL to give a person to review.

Thanks,

I'm not familiar with https://paste.fedoraproject.org . Guessing I need to 
register first but then what? Doesn't appear to have a subject area. Do I just 
post the files you recommended?

Earlier in this thread, you indicated that you saw "warning hostname 
localhost does not resolve to address 127.0.0.1" in /var/log/maillog, 
and some other logs indicated that postfix was timing out connecting to 
its locally hosted domains.  Both of those suggest that you have DNS or 
network related problems, and not something resulting from package updates.


You might consider posting /etc/resolv.conf, /etc/hosts, 
/etc/sysconfig/network-scripts/ifcfg-, and 
/etc/postfix/main.cfg on https://paste.fedoraproject.org/ for review.  
It would also be useful to see the output of "ip addr show", "ip route 
show", and "ip -6 route show".  If the system starts working suddenly, 
as it did earlier, compare the output of those commands when the system 
is working to the output when it is not.

Gz!! Its working again. All I did was restart the system.

I stopped and restarted postfix, dovecot, mariadb several times over the
past couple days. Pretty sure I did a system reboot a time or two.

Decided to do one a few minutes ago and now its working. Hate I never found
the problem that caused this issue!

Thanks for all the help!!

Yes, that's how Maildir mail works - delivery to a Maildir folder means
that the mail is put in Maildir/new until it is seen, when it is moved
to Maildir/cur via Maildir/tmp - it's complicated, but it's necessary
in order to maintain appropriate locks on the files when multiple
clients are accessing them.

When you say "can't login" - what is the error?

What do the dovecot logs say? You can see where dovecot logs to by
looking in /etc/dovecot/conf.d/10-logging.conf - can you see your
roundcube install attempting to authenticate?

This is new information.  It points to the issue being in dovecot or
roundcube.

This indicates that dovecot is working.

It won't, this setting only applies when you're using the postfix
local(8) delivery agent, but you have postfix configured to use dovecot
so this setting does not actually do anything.

> Still can't login to roundcube.

Check roundcube settings, check dovecot logs.  See my previous email for
where to get more help with dovecot.

Based on that I can see pickup receives the message from the sendmail
command (which in turn receives it from the mail command).  The message
is then passed off to amavisd-new which scans it, passes the scan and
re-injects it back into postfix.  Postfix then passes the message off to
dovecot-lda for delivery.  There is no indication in the logs of what
dovecot is doing with the message at this stage.  So it appears that
postfix and amavisd-new are working correctly and if there's a problem
it's in dovecot.

For whatever reason dovecot is not logging to maillog (it may be logging
somewhere else).  You need to find your dovecot logs and trace the
message through there to see what happens next.  I am not so much of a
dovecot expert myself (I use it but I don't know it in as much detail as
I know postfix, for example).  I would suggest posting to the dovecot
mailing list, or you can join the freenode IRC network and ask in the
#dovecot channel where you should get some relevant help.


Good Luck,


Peter

Where does that come from? An HTTP adddress has no valid function in 
SMTP communication.

Even the domain seems to be a typo.

In one terminal: "tail -f /var/log/maillog" or "journalctl -f"

In another, "echo test | mail -s test your@email.address"

What do you see in the maillog at that time?  What does the "df" command 
output?

Happens frequently to me and I'm no open relay.

CentOS uses spamhaus and spamhaus blocks entire subnets if someone on 
the subnet spams.


So unless you can afford your own subnet or pay to be on a whitelist, 
blacklists are a common thing for the little guy.


So much for net neutrality.

Why are you top-posting?

And another reason it may be blocked is the same reason *I* get blocked a
few times a year: those spam blockers that block mailhosts. 20 years ago,
sure. But when you have a domain hosted, as I do, at Hostmonster, and
since I'm not paying for a business account, there are literally tens or
hundreds of thousands of domains whose email is going through them, I
don't care how many admins you have, you can't keep up with the scum...
and so EVERY SINGLE BLOODY DOMAIN'S EMAIL in all those is blocked.

They don't seem to look for "spam from many domains from the same
mailserver", just "is a lot of spam coming from that mailhost".


There is one brain dead commercial spam blocker that analyzes percentage 
of spam vs ham comping from particular IP. On the basis of what all or 
any of their customers get from that IP. Barracuda. Many have heard "we 
have been barracuded".


We were barracuded once. Someone got his address into many spammers 
databases. When he moved to different institution, we set his mail 
forwarded there. Our spam filter back then worked this way: we analyze, 
and label what is spam, and upon delivery it is sorted away into spam 
box. (But all is delivered to recipient, that's the user's right to see 
all coming to one's address). That other place used barracuda.com. And 
our Dept mail server was "barracuded". On the day of deadline of email 
based grant submission to their institution. I got in touch with their 
admins and they "un-barracuded" us. But ever since I do not forward 
email of people who left Department for that particular institution.


The only other exemption we have: I don't forward mail of people who 
left the Department to that one very popular mail provider. You will 
easily guess it once I describe the incident which it is based on. When 
email is being delivered to us after RCPT TO: <> SMTP command we 
know if we have to forward that message, before we continue this session 
we open new session with destination, and once we know from them it is 
deliverable, we accept messages, and immediately pass it over to next 
server. And that one provider always accepts messages even addressed to 
existent addresses on their side, but for addresses that do not exist 
they come back later with undeliverable. And that last puts my mail 
server in a position of the source of backscatter. By this point in the 
story my sysadmins friends whom I described the incident we had guessed 
the provider: gmail.com. Some of them laughed: of course, they first 
collect information, then do actual mail service job ;-) Anyway, people 
who are here do set forwarding wherever they want, people who left the 
department can forward wherever but two exemptions.


As always, on can have a lot of fun troubleshooting email service.

Valeri



I first ran into that in the early oghts, when one of them blocked ALL
EMAIL from Chicago roadrunner.. which was most of the folks online in the
entire city of Chicago.

What do you see in the maillog at that time?  What does the "df" command

Re: [CentOS] Mail has quit working

[Mike McCarthy, W1NR]

Your IP address is flagged as spam in Real Time Block Lists. Are you
using a dynamic IP address? You may have a mis-configured server that is
allowing spammers to relay through your server. Another possibility is
your system is compromised with a spambot.

This is pointless because he's complaining about cron and system emails
which use the sendmail command are submitted through the pickup service,
not port 25/smtp (in fact, if you're submitting any mail via port 25
you're doing it wrong but that's another discussion).

TE Dukes:

Please do the following (lines that start with # should be run as root,
lines that start with $ should be run as a local user):

Install the mail command which is an easy interface to the sendmail
command and thus the pickup service.

# yum install mailx
# tail  -n0 -f /var/log/maillog

then in another window (replace someu...@example.com with your own
email address):

$ mail -s 'Test Email' someu...@example.com <<< "This is a test"

 wait a minute for postfix to have a chance to process and send the
message, then break out of the tail command and copy/paste the output
into your reply.

Then also copy and paste the output of the following:

$ postconf -nf; postconf -Mf

If I need any more info after that I'll let you know.

If your grabbing text and stuffing it with the mouse, you need to send
only 1 line at a time and wait for a reply for each line, except for the
data section where you can send multiple lines.  If you get errors, run
script before running telnet and post a log of the session or else tell
us which line caused the error.

Simply telnet to mailserver on port 25 and type what I've shown,
substituting valid email addresses and valid addresses in your domain as
indicated. You can use your own domain for the hello command, i.e. "helo
mydomain.com".  Everything between the data command and the '.' is input
to the data command.  After you type the '.' the message will be sent
and should be delivered to the user on the "rcpt to" line.  You should
see logging of successful delivery or errors in the maillog.

More information would be helpful to troubleshoot this.  Try sending
output from:

postfix status

mailq

Try telnetting to your smtp server and sending a message like this from
the local system:
substitute a valid user/domain on the mail from line and a valid email
address in your domain
on the rcpt to line. Do this, logged onto the mailserver.

telnet localhost 25
helo mydomain.com (substitute a valid domain here)
mail from: 
rcpt to: 
data
From: someu...@validdomain.com
to: youremailaddr...@yourdomain.com
subject: test

This is a test mesage
.

note: blank line between mail headers and body

end data with line containing only '.'.

Then check your maillog and send the output to the list.


Nataraj

postfix status:

postfix/postfix-script: the Postfix mail system is running: PID 5936

mailq: Mail queue is empty

Did the telnet localhost 25, it answered but not sure I understood you
what I needed to do.

Hello,

Mail has come to an abrupt stop. Running C7, postfix and dovecot. Using
Roundcube as the client.

Mail stopped working Saturday and I cannot figure was has happened. I 
have
not touched this server except to upgrade packages. I believe Roundcube 
was

updated maybe a week ago but know I was getting mail since then.

Crond is no longer send mail. I checked /var/spool/mail as well as 
/Maildir

in home directories. Zero byte files.

Checked all logs and the only thing I could find was  in 
/var/log/maillog :

warning hostname localhost does not resolve to address 127.0.0.1

I corrected that by changing inet_interfaces to localhost from all in
postfix.cf

When I try to log in with Roundcube, it just times out.

I'm stuck!

TIA for any suggestions!!

Are you sure you're not out of disk space?
