Hi,
SPAM is not a big deal if you are getting only SPAM. It is much worse when
you are getting thousands and thousands of failure messages.
This is exactly what happened to me: some smart guy has a huge list of
emails addresses which are intended to be his spam victims. Tousands of
them are not working any more, because the list is out-dated, but the
error messages have to end somewhere, don't they?
Ok, we pick up some existing domain.com and then we wiil randomly generate
[EMAIL PROTECTED] So, all this mess ends up in the postmasters mail.
Apart from these, you find there also tons of threats that people will
suit me for spamming.
My question is:
1) is there a way out?
2) can qmail reject email based on "Received: " envelope? I want it not to
bounce a message back, if there is the bad.host.com listed in the Received
line.
Thank you for you suggestions and comments,
Sincerely
Petr Danecek

Are your server being used as a Relay for these messages,
or are the SPAMMERS simply using your domain to forge their envelope sender.

Yes, it's however mighty complexed and for most people unacceptable.
You have to "compromize" your security so that your service to your users
are balancing right where you and your users are happy,
secondly you have to "compromize" security to insure that your work day
is less than 24 hours everyday while still making your server maximum safe.

You can only purge them automaticly, I'm not sure that's to smart.
The best is to reject based on envelope sender or recipient,
that way you can tell the "offening" server that you rejected the message.
(This is done throug the files control/badmailfrom and control/badrcptto.)
BTW: would it be possible to see one COMPLETE
bounce message you are having trouble with.

The latter. (It happened to quite a few domains in .cz, lately. I have
been busy accepting, refusing and deleting a gigabyte of
bounces/double-bounces over our pathetic 64kbit line for most of
the previous week.)

badmailfrom doesn't help as all the incoming messages are
bounces, MAIL FROM:<>
badrcptto might help, together with some heurestics. (There were
way-too-many forms of [EMAIL PROTECTED]) goodrcptto might
help better :-)
I just changed my ~alias/.qmail-default to
|fastforward -d /etc/aliases.cdb; exit 0
to keep my mailbox clean (and my old harddisk from suffering,
queue from growing, and the load never was more than 4.55 :-) -
most of the load coming (probably) from SYN cookies).

I have stored about five thousand of them. The basic pattern is
simple: Some faked Received line, then someone at
saturn.bbn.com (a DSL? dial-up?), then some open relay in .cn, .jp
or .kr domains (I have seen quite a few of them) and then the
recipient, bouncing the message back. I can post one of the
messages, but which one? Don't want to be unfair to the remaining
open relays :-)
A few people suggested to sue the spammer for misusing
antek.cz's name. Can anyone suggest how? I am not US-based
and our company is not US-based. Is it a crime to fake the return
address (meaning I can mail my evidence to the authorities) or am I
on my own to sue the spammer? If the latter, I can see no chance
of that happening...

Badrcptto does not look at the 'Received:' lines, does it?
A good solution might be to patch qmail so that it will not bounce a
message back if it sees a suspicious 'Received:' line in the header. What
is the best way to do this?

Yes, this is the same guy. All emails' source looks like
PPPa14-ResaleKansasCity1-4R7102.saturn.bbn.com

Usually you would contact people responsible for the domain
saturn.bbn.com. No responses so far.

For now I recommend putting all known forged addresses in badrcptto,
this is the only "easy" way to avoid any high volum traffic over a 64kbps line.

I don't believe badrcptto is a valid control file (at least not for
qmail). Is it part of a patch? Is it an undocumented *feature*? :-)
So, unless it is part of something you have crafted or an add-on to
qmail then it is probably not being used at all...

If this address is in the "MAIL From:" you can give my SPAMCONTROL patch a
trial. Here, you are free to do as pattern match on the sender.

Anything in .saturn.bbn.com is a dialup port sold to a virtual ISP, that
is, a company which may or may not own any modems of their own, but buy
access to Genuity's (formerly BBN's) dialup pool.
We don't have any particular control over them, but every single user
is a client of one of our clients, and our contracts have strong anti-spam
terminology.
Problems should be sent first to the client ISP, if available from headers,
and if not, to [EMAIL PROTECTED]

Thanks for the advice.
</sarcasm>
In that case, you might want to ask what happened to report
BBN-DDQV54204. I haven't heard a word from bbn.com, except the
automatic ticket.
I did report it more than a week ago, at the moment the first double
bounce appeared in my mailbox.

I've been watching this thread on the sideline, and it seems to me, that
the problem is that your box accepts to receive mail to adresses that
doesn't exist on your server, and thus floods your postmaster (you) am i
right?
If this is so, then all you really have to do is this:
remove .qmail-default
make .qmail-postmaster inot a script that looks up if the reciving
adress is valid, othervise send it to /dev/null

The storm is (fortunately) over. I have solved the load on the box by
changing my .qmail-default to
|fastforward -d /etc/aliases.cdb; exit 0
It kept the load down, and kept my inbox (almost) clean.
But still the trafic was killing the line. (And, for the record, refusing
the data after seeing RCPT TO, before accepting DATA, with alikes
of "badrcptto" patch, might cut the bandwidth down by perhaps 30
or 50%, but would not solve the problem.)
[What really hurts is that we're paying each transmitted megabyte.
Fortunately, the ISP agreed to waive about 40% of the usual price
for these extra megabytes. You know, the ISP has been hit by the
same spammer, faking also their domain as a return address...]

-Dave
tnx Dave,
I'll explain it again.
I've a Redirection service in Argentina. (web.net.ar)
We redirect subdomains (pepe.web.net.ar) to the user
personal home page in, for example (members.xoom.com/~pepe).
That's Ok.. only web.
But we (with Sendmail) redirect the subdomain mail too.
[EMAIL PROTECTED]
to for example [EMAIL PROTECTED]
We are changing server's (http://wna.szysz.com.ar) so I install qmail
(Qmail+MySql)
the POP3/SMTP is doing great.
But I couldn't find the way to do the same we do with Sendmail.
We have 1600+ clients. in a Database (MySql), they aren't static. So I've
New clients every day.
I Don't want to create a localuser for each, because they dont check mail
here, I only want to redirect, to rewrite the TO: address.
I try it modifiing the control files but I coundn't find the way.
I was thinking in touching the code... but is very complex.
Any Solution?

control/virtualdomains:
pepe.web.net.ar:alias-pepe
~alias/.qmail-pepe-default:
&[EMAIL PROTECTED]
So for each subdomain you need one virtualdomains entry and one .qmail
file. If that's unacceptable, you can do something like:
control/virtualdomains:
pepe.web.net.ar:alias-subdomain-pepe
~alias/.qmail-subdomain-default:
|script_that_looks_up_pepes_address_in_db_and_forwards_to_it
Which will requires one virtualfomains entry per subdomain, but only
one .qmail file.
-Dave
Tnx Dave,
I'll try this, and the fastforward solutions today.
I'll inform the list the result.
Thanks a lot.

What you can do is create a second profile and restart messenger when you have
to change to a different account. I have been doing that for years. (Once you
have more than one profile you can select them at startup.)
I considered this a small inconvenience for staying away from crap like
Outlook Express...
This feature however has been added in version 6.0 which is in beta right now.
Don't worry, be Kneppie!

Urban legend. There have been studies that show QWERTY isn't all that
bad. _The Economist_ in particular ran a story about a study comparing
Dvorak and QWERTY and found no advantage either way.
The misconception comes from the statement that the keyboard was
designed to slow typists down. Not quite. It was designed to prevent the
hammers from getting tangled up. Doing so doesn't necessarily mean the
typist will be slower.

Thanks for the pointer; I know I've seen several debunkings of the
Dvorak claims, but I couldn't lay hands on one quickly when Brett's
claim came through.

All the very-fast typists I know use Qwerty (and I know one who tests
over 150 WPM).

Have you tried doing a manual SMTP session with the other machine? That is,
have you tried telnetting to port 25 and entering a few SMTP commands? If
this doesn't work, then your problem probably isn't specific to qmail
(perhaps a routing problem). Try it and find out.
---Kris Kelley
Upon more inspection it was actually the remote mail server that was
causing problems. The server I was trying to send messages to has to
NICs one on 213.87.7.* network and the other on 195.40.11.* network, but
as the qmail server was also on the 2131.86.7.* network this confussed
the remote server, and it rejected the connection. i.e. It expected
213.86.7.* machines to connect to its NIC on the same network, not to
the NIC on the 195.40.11.130.
Thanks for all the sugestions.

ICMP - The protocol that likes to go: PING!
Hello,
I have set up "~/control/defaulthost example.com" to send all outgoing mail
as [EMAIL PROTECTED], regardless of what the user enters in his email
client. I want to force this, with the exception of one user who uses
multiple addresses such as [EMAIL PROTECTED], [EMAIL PROTECTED], and
[EMAIL PROTECTED] depending on who he is sending the email to. It's not
really an option to put environment variables on his machine and make him
change them everytime he wants to send an email with a different outgoing
address. Is there a way to achieve this with the qmail control files?
Please advise.
Thanks,
Mike
Greetings,
I use Netscape Messenger quite extensively and I noticed that when I
setup mail filters, there's a greyed out box indicating that it knows
about server side message filters ... is there a module for qmail that
enables this feature?

Is there a way to make qmail defer messages in the event of an NFS outage
that does *not* involve creating a user database?
The project I am working on involves three mail servers, each with an NFS
connection to the user directories. No user information is stored locally
on any of the machines; I use a modified version of qmail-getpw to validate
user names via the network (my company is willing to sacrifice the necessary
local bandwidth for this to work). Because there is no local storage of
information, keeping the user database updated would involve a periodic
query across the network for an updated list of user names. My company
feels/hopes that we will be servicing enough users to make this approach
impractical, as users will be constantly added and removed from the system.
So far my results have been successful. All is well when the network is
behaving itself, and qmail defers messages properly when qmail-getpw fails
due to a bad network connection. A contingency for a failed NFS mount is
one of my last hurdles to getting this all in place. I'm open to any ideas,
from .qmail tricks to code patching.

Ok, let's do this out of order.
.qmail tricks - doing a deferral from ~alias/.qmail-default if the user
seems valid?
Or, *duh*: the homedir check is in qmail-getpw. Since you've already
modified it, modify it some more :)

Right. But he may not actually have to check for the existance of HOME currently
and in any event there is a timing window between qmail-getpw and the
invocation of qmail-local. So it may disappear after the check in qmail-getpw.
Having said all that, qmail-local exit with a *temp* error if it cannot
stat the home directory, so I'm not sure what the exact problem is. If the
nfs home is gone, then this stat() should fail at some point and defer
the delivery.
The only general problem is that the NFS timeouts may clog the concurrencylocal
limits, but then if you have no homes, there's nothing to delivery anyway.
code frgament:
if (stat(".",&st) == -1)
strerr_die3x(111,"Unable to stat home directory: ",error_str(errno),". (#4.3.0)");
doc fragment:
111 means that the delivery
failed but should be tried again in a little while (soft
error).
Regards.
since you have already gone into qmail-getpw.c,
play with it a bit more. what we did was modify
it to exit 111 if a control file exists in /var/qmail/control/...
hmm. i guess this only works when you know ahead
of time you'll be bring stuff down or have noticed a
major problem occurring. markd seems to have a
good solution for intermittent NFS problems.

That's what I thought, I considered a race attack, but there is none.
qmail-local *defers* on homedir failures. Only qmail-getpw actually
*bounces* on homedir failures.
He's using a *modified* qmail-getpw, not a rewritten one. The homedir
check is probably just still in there.

Yeah, that's because qmail-getpw does the bouncing.

That depends. Where I work we have homedirs spread over about 40
userservers, which means indeed one can be down while the others are up.
I modified my checkpassword replacements (which uses files in the
homedir) to kill itself after 1 second, just because of broken NFS
stuff.

Hmm nice thought, that means remote deliveries are still working, and
the todo queue isn't growing either because you don't have to shutdown
qmail itself.

Nope, he's missing points. Modifying qmail-getpw is the way :)

Makes sense. Okay, so if I make qmail-getpw either not do a directory
check, or handle the results differently, then there shouldn't be any lost
or bounced email, even if the NFS mount happens to disappear between
qmail-getpw and qmail-local. Correct?

There will only be one server for user directories, at least to begin with.
So, yeah, hitting the concurrencylocal limit won't be an issue.
Michael Boyiaz's idea is a good one too. Sounds like it would make planned
outages easy to wade through.
Thanks for the input!

Correct.
If you're using users/assign, qmail-getpw is skipped, but qmail-local
isn't. Empirical proof that qmail-local doesn't bounce on broken homedirs :)

Hello all,
Problem 1: When starting qmail under svscan via the startup script (I'm
using Life With Qmail as my guide), I get errors complaining about being
unable to acquire a lock of certain files:
Supervise: fatal: unable to acquire qmail-send/supervise/lock: temporary
failure
Supervise: fatal: unable to acquire log/supervise/lock: temporary failure
Supervise: fatal: unable to acquire qmail-smtpd/supervise/lock: temporary
failure
Supervise: fatal: unable to acquire log/supervise/lock: temporary failure
My guess is that this is a permission or ownership problem? I tried
chmodding the directories the lock files are in to 777 and deleted the lock
files, but no dice. Any ideas?
Problem 2: When I manually start qmail (no svscan running), I am able to
connect to port 110, but only for a moment. It immediately disconnects me
like so:
Trying my.ip.address...
Connected to dellhost.wierd.ip.address (my.ip.address)
Escape character is '^]'.
Connection closed by foreign host.
I am able to manually run qmail-popup like this:
/var/qmail/bin/qmail-popup host /bin/checkpassword pwd
Do you think my problem has to do with my pop3 entry in inetd.conf? What
should my entry to inetd.conf look like? Thanks for any help anyone can

Hello everyone,
I using qmail 1.03 with vpopmail and sqlwebmail.
Question 1 - When I add a new user via qmailadmin I see the user in
/var/vpopmail/domain/nameofdomain/user. but the /var/qmail/users/assign
file only has one entry (the one it created when I added the domain. Is the
assign file supposed to be updated every time I add a new virtual user. I
manually run qmail-newu, no luck.
Question 2 - Every time I send a email to a virtual user it get stuck in the
queue and the log file says "unable to change dir #4.2.1
I'm running the pop3 daemon as vpopmail.
Any help would be greatly appreciated
TIA

I've set-up pop3d using supervise and tried to get it to log
/something/, however nothing ever comes out. I'm very interested to see
the number of concurrent connections similar to the way the other qmail
programs do (send and smtpd). Any way to do it?
Here's my pop3d/run file:
#!/bin/sh
QMAILDUID=`id -u qmaild`
NOFILESGID=`id -g qmaild`
exec tcpserver -R -x/etc/tcp.pop3d.cdb 0 pop3 \
/var/qmail/bin/qmail-popup mail.vcnet.com \
/var/qmail/bin/checkpoppasswd /var/qmail/sbin/relay-ctrl-allow \
/var/qmail/bin/qmail-pop3d Maildir 2>&1
Here's my pop3d/log/run file:
#!/bin/sh
exec /usr/local/bin/setuidgid qmaill \
/usr/local/bin/multilog t /var/log/pop3d
I take it qmail-pop3d just isn't verbose like qmail-send and
qmail-smtpd?

I have sent this earlier note to test duplicate subscription. It looks like
qmail list server accepts subscriptions from the same address without checking

copies.
I don't know who the list admin is, but I hope he sees this note.
Thank you.

You might check the full headers of each of the apparent duplicates. More
than likely, the Return-Path: header will differ; usually, you have more
than one address subscribed to the list.

Hi all,
I am just starting to build our first qmail internet email server, and am
having alot of problems with getting qmail to run.
Basically everything about qmail works. I've gone through the INSTALL file
and am running Maildir and all mail locally on the server is working fine.
It's the setting up of the pop mail services that has me stumped.
Ive taken the steps from the FAQ regarding pop3d setup, and have installed
tcpserver and checkpassword successfully, but still no luck. I've entered
the following into SUSE's boot.local file: (As told by the FAQ - domain is
an example)
tcpserver 0 pop3 /var/qmail/bin/qmail-popup qmail-popup lisp.com.au
/bin/checkpassword /var/qmail/bin/qmail-pop3d Maildir &
(all in one line)
But that just makes the system lockup and eventually time out when the
boot.local service tries to run upon system startup. Now, the FAQ states
that if tcpserver is installed then you shouldnt have a line in the
inetd.conf file on pop3. So I have removed the line as shown in the FAQ:
pop3 stream tcp nowait root /var/qmail/bin/qmail-popup qmail-popup
lisp.com.au /bin/checkpassword /var/qmail/bin/qmail-pop3d Maildir
Even though if I have this line running and the boot.local line removed the
system boots ok, and i can check mail from another computer via email
client software (O.E.5), i just cant send.
I'm running SUSE 6.4 with qmail 1.03. If SUSE is the problem then someone
please tell me that SUSE is no good and that I should switch to redhat.
Any help in this matter would be appreciated eternally. Better yet, if
anyone knows of good docs on setting up "qmail for internet email" then
could you please let me know.
Regards,
Daniel

Hi Daniel
I was faced the same problem two months ago and I was provided with
great help from the list. My big problems were problems in the config
files. Especially your tcp-server problems seem to occur for this
reason. So I sent you my startup script for tcpserver. I have the same
Configuration as you so you should have not a big problem to adapt it to
your setup.
Just call it in the appropriate rc.x level and everything should be
fine.
The documentation you asked for is Dave sills Life with qmail. I think
you yet found it. When I had problems I was also looking for further
documentation but finally I discouvered that you could really everything
to work with LWQ.

Please teach me how should I control with qmail server to be able to be received
mails only through the router on witch Virus check is active.

G'day all
I'm in need of some sanity. Does a patch exist, or does anyone want to make
one, to make multilog rotate logs based on time rather than file size? I
hope that I don't even have to start explaining why...The word
'standardisation' comes to mind. It's like comparing America to Australia.
Why do America have to make everything back-to-front for us? The same goes
for multilog... I want to be able to archive logs easily, analyse them
easily. Tell me how I can do that if I am limited by file size. A bulk
e-mail that I'm not expecting will wipe my files out of existance. Sure I
can make the number of files I keep bigger, but is that really a fix? More
its an unnecessary hassle getting in the way. Using tai64 time format, I
kind of understand. It makes some degree of sense, even if it is annoying to
read straight out. But size-based log rotation with no option for time? OK
someone's been smoking some big time drugs here... Oh and before you say try
the !processor directive, I did but to no avail...There is probably a whole
paragraph of information on it spanned across the Internet. Great. No
examples anywhere really though...
Thanks for perusing this query

do there exist any solutions for clustering qmail to build high-volume-servers
??
i`m looking for some tools or patches to do load-balancing, put pop-boxes on
more than one server, use more than one smtp-server...
help???
thx

There are several server load balancer solutions available. I use the
'ServerIron' product from Foundry Networks (www.foundrynet.com), it seems
to perform very well. You also have Alteon (www.alteonwebsystems.com),
cisco, and others.
These boxes are regular layer-2 switches. In addition to
switching packets like other switches, they perform load balancing.
One way they can do this is to reply to ARP requests
for the IP addresses your mail server is known by on the Internet.
Your router will therefore send all incoming IP packets to the ethernet
address of the switch. The switch will pick up a packet, choose the
front-end mail processor (FEP) it thinks has the lowest load at the moment,
put that ethernet address on the packet instead of its own and put
the packet back on the wire for the FEP to pick up.
The switch also monitors the FEP's and routes connection requests to
other working servers if a FEP is discovered to be faulty. This makes error
situations and maintainance downtime invisible to the clients.

None as such..I have been meaning to write a HOWTO for something similar but
this year has just been crazy...maybe next year. BUT some suggestions:
- Look into a NFS/NIS combination (I use this for a distributed e-mail
system currently spanning a city, soon to be spanning several locations on
the planet)
- AFS (Andrew File System) also looks interesting for some real hard-core
distributed, clustered work
There are probably other ideas, but those are the two I would look into
first.
