temporary rejection

Hello everyone,

I wonder if and how its possible to make qmail temporarily reject mail
for a certain virtual host. An alternative would be to forward all the
messages to another mail server for storage for a single virtual domain.

I would be grateful if somone could give me a hint how to accomplish it
or where to look for documentation.

Best regards,

Oliver Block

Problem configuring qmail

Hello,

I am having a problem here. I had a qmail installation set up and running for a few years. Now a disk crash
ruined the whole thing, for sure the backup is not readable :-( and I cannot get it running again.

I have the following configuration:

Clients (various Mail clients, SMTP, IMAPS) -----------v
					|	Mail server (Sendmail)
					|	       ^
					|	       v
					\----->	Qmail-Server
						  v        ^....^      
						internet   mail-domains

The setup was the following:
Mail comes into the Qmail-Server via SMTP and fetchmail/SMTP from different domains.
The qmail-server delivers to the mail-server with the post boxes.
The clients fetch their mail from mail-Server with imap(s).
They send their mail directly to the qmail-Server using SMTP.
The qmail-server delivers mail using my providers SMTP-Gateway, which requires AUTH extension, which
works with no? problem. I am using SMTP-AUTH send patch from Bjoern Kalkbrenner.

What should work:
Mails from one client to every other.
Mails from the client to the outside world.
Mails from the outside world (various domains) to the users.

Now to the problems:
Every Mail I try to send from a client to another client gets sent to the provider.

Separate delivery by MX record in DNS. Point the MX record of the
"virtual domain" to your secondary storage server (which needs to have
a configured SMTP daemon running on port 25).

You could also add a second IP to your primary qmail and run separate
tcpserver instances.

Stop multilog

Hi,
I'm on gentoo 2006 64bits

My qmail initialization script looks like this :

    ebegin "Starting Smtp"
    env - PATH="/var/qmail/bin:/usr/local/bin" CHKUSER_START="DOMAIN" \
        tcpserver -v -H -R -x /etc/tcp.smtp.cdb -c100 -u508 -g503 0 smtp \
        /var/qmail/bin/qmail-smtpd 2>&1 \
        | /usr/local/bin/tai64n \
        | /usr/local/bin/setuidgid qmaill /usr/local/bin/multilog
s500000 n60 /var/log/qmailsmtp/ &
    eend $?

I want to stop this process because i think a service is reloading
this process when i kill it
qmaill    2512  0.0  0.0   2568   404 ?        S    Apr02   0:01
/usr/local/bin/multilog s500000 n60 /var/log/qmailsmtp/

I don't know which service can stop multilog
If someone could help me...

Thanks !

Regards
C.

Re: temporary rejection

Unfortunately, DNS modification is no option. I forgot to mention that.

So you run a mail server and have no control over the DNS? That's sad.

Why on earth do you want to do that? qmail-smtpd will block after its 
log buffers are full.

Meaning... (this is a guess) your clients could choose whether to use 
the sendmail server or the qmail server as their outbound relay?

And those post boxes are where? The sendmail machine?

Okay. This seems a little overly complicated, but <shrug>.

If I'm reading that correctly, you've told it to spawn a new instance 
of multilog for every connection. That is an absurd 
configuration---multilog LOCKS the log directory (for good reason) and 
will simply exit if the directory is already locked. So what probably 
happens for you is that you never get log entries for concurrent 
connections.

The *correct* way to do that is to either use daemontools (so that 
multilog can be used in a sane manner) OR to use splogger (which feeds 
the log entries to syslog).

That's easy: simply remove that virtual host's domains from the 
rcpthosts file (and/or morercpthosts, if you use that).

Honestly, that's significantly more complicated (unless you have 
control of DNS).
