Fixing Qmail 451 qq temporary problem (#4.3.0) / @4000000050587780174c60dc status: qmail-todo stop processing asap / status: exiting

Wednesday, September 19th, 2012

I’m in process of installing plain new Qmail mail (SMTP) server following QmailRocks updated: Thibs QmailRocks install guide for Debian 6.0 Squeeze
The install went smoothly so far and I’m already doing this installation for about 5 hours or so. I’m done with the minor install and following Thibs instructions to Implement validrcptto feature to Qmail.

Anyone who works with Qmail, should already know the lack of validrcptto tons of SPAM problems and useless Qmail load, because of QMAIL attempts to delivery to the local mail server unexisting mail boxes ….

Fixing this whole mess is implemented with the validrcptto. I myself has installed numerous times validrcptto and almost ever I ended up in some kind of mess before fixing it once and for all, this time of course (quite traditionally) the “story” repeated to piss me off for a while 🙂

After following steps literally as described on Thibs great Qmail install tutorial!, I ended up with a Qmail mail server unable to deliver properly e-mails.

To debug why mails are not properly delivered by the mail server I used telnet:

root@qmail-host:/var/qmail/control# telnet localhost 25
Connected to localhost.
Escape character is '^]'.
220 This is Mail Pc-Freak.NET ESMTP
HELO localhost
250 This is Mail Pc-Freak.NET
250 ok
250 ok
354 go ahead
451 qq temporary problem (#4.3.0)

Some time, back while configuring another Qmail fresh install, I ended up with exactly same delivery error – I’ve take time to document how I fixed this weird qq temporary issue here

As I thought one error in “normal” Software can correspondent to one cause, I red my previous post and checked closely all that was in past wrong whether I encountered the err; guess what this time it wasn’t due to non-running (missing) clamav-daemon. Still though this was not the issue, it partially pointed me to the cause (problem with / spamd /pyzor / razor / dcc or whatever of this overall complexity ..).

First logical think was to check in logs. In /var/log/qmail/qmail-smtpd/current everything was looking good; my log looked like so:

root@qmail-host:/# tail -n 10 /var/log/qmail/qmail-smtpd/current
@40000000505877b91ab3aba4 tcpserver: end 23727 status 0

@40000000505877fd1a3c647c qmail-smtpd[23882]: MFCHECK pass []

Second guess was to check in /var/log/qmail/qmail-send/current, there found errors like:

root@qmail-host:/# tail -n 10 /var/log/qmail/qmail-send/current
@4000000050584f8e0b799194 status: local 0/10 remote 0/120

s you can see yourself, the errors are not giving any insight on what could be the reason, so I checked in /var/log/mail.log, just to find more errors there:

Sep 18 16:22:04 qmail-host X-Qmail-Scanner-2.10st:[pcfreak134797452279623171]

d_m: output spotted from /usr/bin/reformime -x/var/spool/qscan/tmp/qmail-host/I134797452279623171/ (sh: /usr/bin/reformime: not found#012) - that shouldn't happen!

As the error points out, the whole issues are caused by missing binary – /usr/bin/reformime. Logically I had to install reformime, so did a quick apt-cache search reformime and saw reformime is part of maildrop deb package. I thought it is installed but after checking with:

dpkg -a |grep -i maildrop

Realized it is missing and install it:

qmail-host:/# apt-get --yes install maildrop

That’s all after a qmail restart, i.e.:

qmail-host:/# qmailctl restart
* Stopping qmail-smtpdssl.
* Stopping qmail-smtpd.
* Sending qmail-send SIGTERM and restarting.
* Restarting qmail-smtpd.
* Restarting qmail-smtpdssl.
* Restarting qmail-pop3d.

qq temporary error got solved and from there on qmail received and sent mails normally with validrcptto enabled. Cheers 😉
