RE: virtual mailbox domains??

2021-12-09 Thread postfix

Thanks *so much* for all your help.

Another complete rebuild and I think I’ve finally got it.

I was able to log into mail.sizzelicks.com for smok...@sizzelicks.com 
<mailto:smok...@sizzelicks.com>  this time with no trouble.

I sent an email to smok...@sizzelicks.com <mailto:smok...@sizzelicks.com>  from 
a gmail account and was able to retrieve it in Thunderbird.

I replied to the gmail email and in gmail.com I got the response.

Now I can add email accounts to the database for any of our domains and they 
work!

I've added responses below.

The reference to private/auth is referring to dovecot's authentication socket 
under postfix's chroot directory.

It's in /var/spool/postfix/private/auth, not /etc/postfix.

You have set that up in dovecot's config:

  service auth {

unix_listener /var/spool/postfix/private/auth {

  group = postfix

  mode = 0666

  user = postfix

}

unix_listener auth-userdb {

  mode = 0600

  user = vmail

}

user = dovecot

  }

My version of that looks like:

  service auth {

unix_listener /var/spool/postfix/private/auth {

  mode = 0666

}

  }

So it looks like that should be OK.

Does /var/spool/postfix/private/auth exist?

Mine has root as owner/group. Yours should have postfix as owner/group. But 
that shouldn't matter as long as the mode is 0666.

I must of changed the mode to 0660 but per your suggestion I changed it to 
0666. Thanks.

Yes it does exist.

ls -l /var/spool/postfix/private/auth

srw-rw 1 postfix postfix 0 Dec  8 21:50 /var/spool/postfix/private/auth

If not, check dovecot's log messages for problems with it.

But I don't know what to look for. The dovecot mailing list folks might be more 
useful for that.

It should exist and be used by dovecot. If you have lsof installed, you can 
check that:

  > sudo lsof /var/spool/postfix/private/auth

  COMMAND PIDUSER   FD   TYPE DEVICE SIZE/OFF NODE NAME

  dovecot   17341root   53u  unix 0x8e43c69f7400  0t0 16873340 
/var/spool/postfix/private/auth type=STREAM

  auth1521507 dovecot   13u  unix 0x8e43c69f7400  0t0 16873340 
/var/spool/postfix/private/auth type=STREAM

  auth1521507 dovecot   21u  unix 0x8e43c417c800  0t0 69451443 
/var/spool/postfix/private/auth type=STREAM

  auth1521507 dovecot   22u  unix 0x8e43c9fc2400  0t0 69453124 
/var/spool/postfix/private/auth type=STREAM

sudo lsof /var/spool/postfix/private/auth

COMMAND  PID USER   FD   TYPE DEVICE SIZE/OFF   NODE NAME

dovecot 4550 root   58u  unix 0x  0t0 1305802532 
/var/spool/postfix/private/auth type=STREAM

Something else that might or might not be a (different) problem is that the TLS 
certificate at mail.sizzlelicks.com doesn't certify the domain 
mail.sizzlelicks.com. Its list of domains contains sizzelicks.com and  
<http://www.sizzelicks.com> www.sizzelicks.com but not mail.sizzelicks.com. 
That might cause problems with Thunderbird trying to connect for IMAPS. I think 
you reported such an error message earlier. So you might want to add the 
mail.sizzelicks.com domain to that certificate. But that's not related to the 
failure to connect to the dovecot auth socket.

You are correct and I sure wish I saw *this*  a week ago. 

I did a rebuild due to lots of trouble trying to add the certs.

Now I’ve got it all back up with the certificates for all of the 
mail.mydomain.com  MX records.

THANK YOU

cheers,

raf

The reference to private/auth is referring to dovecot's
authentication socket under postfix's chroot directory.
It's in /var/spool/postfix/private/auth, not /etc/postfix.

You have set that up in dovecot's config:

  service auth {
unix_listener /var/spool/postfix/private/auth {
  group = postfix
  mode = 0666
  user = postfix
}
unix_listener auth-userdb {
  mode = 0600
  user = vmail
}
user = dovecot
  }

My version of that looks like:

  service auth {
unix_listener /var/spool/postfix/private/auth {
  mode = 0666
}
  }

So it looks like that should be OK.
Does /var/spool/postfix/private/auth exist?
Mine has root as owner/group. Yours should

RE: virtual mailbox domains??

2021-12-06 Thread postfix

I finally figured out why I couldn't send emails to smok...@sizzelicks.com
<mailto:smok...@sizzelicks.com> .

I am attempting to migrate from shared hosting to a VPS.

My shared hosting account at hostgator.com still had the domain
sizzelicks.com set up.

Every time I tried to send email FROM a hostgator account hostgator
intercepted the message because it hosted (or thought it hosted)
sizzelicks.com.

 

I removed sizzelicks.com from the domains on hostgator and now I can send an
email to smok...@sizzelicks.com <mailto:smok...@sizzelicks.com>  without it
bouncing.

I don't know what happened on the server end. The mailbox folder exists and
dovecot has files in there but I can't say it contains emails.

I still can't connect to the mailbox. I'm guessing that's a dovecot/imap
problem.

 

Maybe you can help me now?

RE: virtual mailbox domains??

2021-12-06 Thread postfix

I have both postfix and dovecot running.

Command: sudo postfix status

postfix/postfix-script: the Postfix mail system is running: PID: 38284

Command: sudo systemctl status dovecot.service

Active: active (running) since Mon 2021-12-06 12:48:45 UTC; 2h 29min ago

 

I've checked all 3 mysql connections using postmap.
They connected with the correct response for sizzelicks.com,
smok...@sizzelicks.com   and
spa...@sizzelicks.com   (alias) like they did
before.

 

I have verified that ufw allows the appropriate ports (see below).

 

I stopped postfix and dovecot.

I cleared the log, then started postfix and dovecot (successfully this
time).

I attempted to send an email to smok...@sizzelicks.com
 . It bounced.

I attempted to connect via Thunderbird to the mailbox of
smok...@sizzelicks.com  .

The mail server set (smtp & imap) was mail.sizzelicks.com.

The error was connection timed out.

 

In the log I see a few attempts to connect from spammers. I do not see my
laptop IP or anything at all about what I did.

You see I can send this email from my laptop just fine, yes?

Also I used telnet from my laptop to sizzelicks.com on port 25 and connected
with no problem.

It returned aecperformance.com which is what I have myhostname set as in
main.cf

The certificate set in main.cf is the certificate chain for my websites (all
working fine under ssl).

To find out if the master is running use "sudo postfix status", 
instead of using systemctl commands.

It was running, according to your logs:

Dec  5 21:33:26 softlinksys postfix/postfix-script[31361]: starting the Postfix 
mail system
Dec  5 21:33:26 softlinksys postfix/master[31363]: daemon started -- version

If the Postfix master is no longer running, then you need to find
out what is killing your Postfix processes.

If the Postfix master is still running, connect to port 25

$ telnet name-of-host 25

And tell us what you get.

RE: virtual mailbox domains??

2021-12-06 Thread postfix

I just stopped postfix and dovecot, then cleared the logs then restarted
postfix and dovecot.

The status of postfix says active (exited). The status of dovecot says:
active (running)

syslog

Dec  6 12:48:45 softlinksys systemd[1]: Started Dovecot IMAP/POP3 email

Postfix is not logging anything at all. This has gone from bad to worse.

You have my config. Please let me know why postfix won't run.

 

 

>From what you post here, I have an impression that you have multiple
problems and are trying to solve them all at once, which usually never
succeeds. Try to debug and solve one thing at a time.

 

First, make sure that DNS records are actually correctly set up and point to
the correct hosts.

Our VPS IP is 194.163.45.150. You can easily check this:

 

https://mxtoolbox.com/SuperTool.aspx?action=a%3asizzelicks.com=toolpage

 

https://mxtoolbox.com/SuperTool.aspx?action=mx%3asizzelicks.com=toolpage

You can check them for softlinksys.com/mail.softlinksys.com also and see
that the IP is the same.

 

Second, make sure that your services are actually running, try checking if
Postfix delivers the mail by telnetting locally to port 25, then checking
logs and checking the destination folder where the mail is supposed to
appear.

It turns out that I can't make postfix run. I start it and then check its
status and it says  active (exited)

 

At the very end, when you are absolutely sure everything is working, you
should try to configure an email client like Thunderbird and check email
sending/receiving with it.

I did and it did not work even when postfix was running. The error was auth
failed

 

Not everything at once!

I've just had another look, and I'm still not seeing
postfix/dovecot running. The only port scan difference
between now and when I last looked is that port 443 is
now open:

Ports 25/587 (for postfix) and 143/993 (for dovecot)
should be open.

Perhaps something is causing both services to terminate
(e.g. The OOM killer?). Check all of your logs (not
just mail logs) to investigate why they aren't running.

RE: virtual mailbox domains??

2021-12-05 Thread postfix

OK, our VPS is back up and running.

If you log

I did the installation of postfix and dovecot from this tutorial.

https://yiworkdisk.netlify.app/en/linux/install_postfix.html

 

Command line tests for msql connections:

sudo postmap -q sizzelicks.com
mysql:/etc/postfix/mysql-virtual-mailbox-domains.cf

1

sudo postmap -q smok...@sizzelicks.com
mysql:/etc/postfix/mysql-virtual-mailbox-maps.cf

1

sudo postmap -q spa...@sizzelicks.com
mysql:/etc/postfix/mysql-virtual-alias-maps.cf

smok...@sizzelicks.com  

 

Mail Host Folders:

/var/mail/vhosts/softlinksys.com

/var/mail/vhosts/sizzelicks.com

 

Postfix and dovecot are installed and when I use the command: sudo service
dovecot restart it starts and returns the cursor with no problem.

 

I just tried to send an email to smok...@sizzelicks.com
  (see above) from MS Outlook on a laptop I
got this:

Server error: '550 No Such User Here"'

I tried to set up a mailbox in Thunderbird for the email:
smok...@sizzelicks.com  

I got a message saying that it could not connect.

 

This time I've got nothing in the logs about trying to send the email or
about trying to connect to the mailbox.

Look above, you'll see that I did connect to mysql for both the domain and
the email.
This time I did use sha512 for the password.

 

I got the certificate from letsencrypt, specifically for
mail.softlinksys.com.

The path to the file was saved in the config for postfix and dovecot.

 

I stopped postfix and dovecot, cleared the log, started postfix & dovecot
(no problem).
Then I tried to send smok...@sizzelicks.com 
an email and then tried to create a mailbox in Thunderbird & connect it for
smok...@sizzelicks.com  

 

It took me less than an hour from a rebuild to set up the firewall, ftp
access, apache2 ssl secured, running php connecting to mysql for multiple
virtual hosts. 

No problem; my sites are running fine.

 

I absolutely *cannot* make the mail server work. I started this Wednesday
before Thanksgiving, 12 hour days - I cannot make it work.

 

Look at: https://sizzelicks.com

 

mail.log

I'll send the configs in multiple emails next.

The virtual domain should be sizzelicks.com (which is
to be used in the email addresses themselves), not
mail.sizzelicks.com (which is just the target of
sizzelicks.com's MX record).

I just tried to send an email to smok...@sizzelicks.com
but the connection timed out. nmap shows:

It looks like neither Postfix nor Dovecot are running
there right now. Could that have been the case when you
tried? Presumably not, or Thunderbird wouldn't have been
able to connect.

If the connection you are referring to is the IMAP
(port 143) connection (as opposed to the port 587
connection), the problem might be related to the domain
names associated with the TLS certificate. Thunderbird
expects the hostname to match the certificate (at least
for IMAP/POP). But if that were the problem, Thunderbird
would connect but it would then probably tell you that
the certificate is invalid and refuse to use it.

The certificate you are using is a LetsEncrypt
certificate for mail.softlinksys.com. Perhaps that
certificate includes the domain sizzelicks.com but not
mail.sizzelicks.com. That might explain why an IMAPS
connection in Thunderbird succeeds with one but not the
other. You can check which domains are include in that
certificate with "sudo certbot certificates". You might
need to add the mail.sizzelicks.com domain to that
certificate (or tell Thunderbird to connect to the
host mail.softlinksys.com instead).

> How can I correlate sizzelicks.com with mail.sizzelicks.com in postfix and
> dovecot.

Not sure, but bear in mind that, even though they have
the same IP addresses, sizzelicks.com belongs in the
email addresses, and mail.sizzelicks.com belongs in
attempts to connect to the mail server, because the MX
record for sizzelicks.com points to
mail.sizzelicks.com. So Thunderbird should be
connecting to mail.sizzelicks.com (or maybe
mail.softlinksys.com). If it doesn't work, check
Thunderbird's error messages. I think it has a
"connection doctor" that you can look at.

> How can I debug/resolve this problem?

Um, you might need a new service provider. I looked at
the webpage for softlinksys.com (the value of
$myhostname) and there's an image of a sign saying:

  "Sorry We're CLOSED Out of business"

Your first step is to get Postfix and Dovecot running on the/a server.
Then you can try to send an email again and look for the relevant
log messages.

Only include the Postfix log messages that relate to
(or happen within a few seconds of) a single attempt to
send an email to that address. Then it shouldn't be too
large. It might help to include any Dovecot log
messages from the same time.

Indeed there is nothing in the logs that shows attempts to receive

Then I retrieved syslog and mail.log.

Real-time access to the full recipient table (be it via LDAP or SQL)
is more reliable/predictable than a partial cache.  Accessing and
caching the data via SMTP/LMTP is perhaps a lower attack surface
than the LDAP or MySQL protocols, but not by much.  My personal
preference in such a situation is to use LDAP or SQL.  With LDAP
you can spin-up a replica service that is colocated in the DMZ.

Yes, virtual_mailbox_domains is for final destinations 
including LMTP, relay_domains for forwarding to MTAs.

Peer may have written some of his text before Postfix

This makes sense. I'm not really relaying the email so perhaps a
virtual mailbox domain makes more sense than a relay domain. Peer
Heinlein also wrote a (very thick) book on Postfix but alas it's only
in German so I will have to translate it before I can read it.

That is exactly what Peer Heinlein also uses in his book but what I
forgot to mention. I like this idea as it better isolates your DMZ
server than when you have your DMZ server access your MySQL database.

So am I correct that the general population would recommend/prefer
virtual mailbox domains over relay domains in this situation?

An alternative to a static table is dynamic recipient verification.
This uses a cache with proactive refresh.

This is not necessary.  LMTP is not SMTP, and you're not relaying
the mail.  And even if you were, the destination is not a store-
and-forward MTA, but a mailstore.  So it is not unreasonable to
model the associated domain as a virtual mailbox domain.  You
can in that case put anything you want in the RHS of the virtual
mailbox table:

user@virtual.exampleVALID

the table is only used for recipient validation, not mailbox
location, which is determined by the mailstore.

That said, much the same works with relay_domains and
relay_recipient_maps.  Provided, with relay_domains, you
are careful with "parent_domain_matches_subdomains" and
avoid accidentally accepting mails for subdomains when
you only intend to receive email for the domain.

I'd be inclined to stick with virtual mailbox.

Losing recipient validation is NOT an advantage.  Either way,
you need to have a table of valid recipients to avoid backscatter.
