I have a Plesk 7.1.5 installation on a RH3EL box, and qmail works fine.

I run this command:

rpm -Uvh qmail-scanner-1.24-1.rhel3.art.noarch.rpm

It finishes without error. I then start to get errors on smtp. Consider this transcript (I made the connection and pasted the input ):

telnet localhost 25
Trying 127.0.0.1...
Connected to localhost.localdomain (127.0.0.1).

220 localhost.localdomain ESMTP
helo world

this is a test

after removing the qmail-scanner rpm, qmail works fine once again.

Any ideas, anyone?

Okay, I havn't solved the issue yet, but I think I've come real close. I hope what I did her helps inspire the rest of the fixes.

As far as I understand, ART's version of qmail-scanner replaces the /var/qmail/bin/qmail-queue binary with his qmail-scanner-queue binary.

The qmail-scanner-queue is a simple C program to exec the qmail-scanner-queue.pl script. The reason I believe he does this in C, is so that the permissions of of the setuid ( 4755 ) stick with the child processes.

Anyway, I wasn't very sucessful in setting enviroment variables from his qmail-scanner-queue.c program, so I altered it a bit. I made that C program, instead, run my own script:

/var/qmail/bin/qmail-scanner-env

This reads:

#!/bin/sh

export LC_ALL=C LANGUAGE=C LC_MONETARY LC_NUMERIC=C LC_MESSAGES=C LC_COLLATE=C LC_TIME=C LANG=C

/var/qmail/bin/qmail-scanner-queue.pl

And it looks like this on the filesystem:

-rwsr-xr-x 1 qmailq qmail 147 Dec 16 07:28 /var/qmail/bin/qmail-scanner-env

So now when i telnet to localhost and do the SMTP routines, I get this:

telnet localhost 25
Trying 127.0.0.1...
Connected to localhost.localdomain (127.0.0.1).
Escape character is '^]'.
220 localhost.localdomain ESMTP
helo world

rcpt to: corman@unstupid.com

this is a test
. 250 localhost.localdomain
250 ok
250 ok
354 go ahead
/bin/rm: cannot remove `/var/spool/qmailscan/tmp/localhost.localdomain11032181336802695/': Permission denied

I believe this is happening on line 1763 of qmail-scanner-queue.pl, which reads:

system("$rm_binary -rf $ENV{'TMPDIR'}/ $scandir/$wmaildir/new/$file_id") if ($DEBUG < 100 && $file_id ne "");

Anyone got any ideas?

Thanks

I finally decided to give it a shot with the C code, and forget the whole shell script workaround.

I was able to set all the env variable to "C", and this is the code that did it:

The issue appears to be solved for me now. Hope this helps others with the same problem.
