Something is wrong here. 
I set up qmail on Mandrake 9.1, which uses GLIBC_2.3 
Works just fine if you make a few changes to the source i.e. cleaning up old 
compatibility code. (replace "extern int errno" by "#include <errno.h>" 
I did everything according instructions on 
<http://www.flounder.net/qmail/qmail-howto.html>, which worked for me in the past. 
Afterwards I installed the qmail-scanner v. 1.16, following instructions from the 
howto like a Japanese kamikaze. 
Everything seemed to work, until this morning I noticed heavy load on my machine. 
There were almost 20000 messages waiting to be delivered! As this was a new, unused 
testmachine which should not have any queue, I checked the messages and saw it was 
spam! Apparently my host had become an open relay and some #ç$^-ing spammers had 
already scanned my host and started using it as a relay (and it has been online only 
since 2 days). 
Checking it from the outside confirmed it: my host was an open relay. 
BUT: my "rcpthosts" file only accepted my local domain, so it should not be relaying 
at all. I searched the whole day, looking for a problem in qmail. 
I finally worked around the problem and thereby found the cause of it: in tcp.smtp, my 
tcprules config file: 
:allow,RELAYCLIENT="",RBLSMTPD="",QMAILQUEUE="/var/qmail/bin/qmail-scanner-queue.pl" 
Apparently, qmail-scanner-queue.pl ignores my rcpthosts file and lets any mail go 
through. I removed the QMAILQUEUE variable, ran tcprules again and now qmail is 
working with it 's default queuer no antivirus, but not being an open relay anymore. 
Had anybody else had the same problem before?
