&tempfail exits with a temp error code. How could it be otherwise? 

The issue of course is that it is the responsibility of the the process
_calling_ e-mail to handle the error. If Q-S notices a problem
internally and exits with a temp failure when dealing with incoming SMTP
email, then the SMTP client gets the temp failure and requeues to try
again. 

However, if you have set QMAILQUEUE within /etc/profile,etc, and a
batchjob calls email and the temp failure occurs, then that error is
propagated back to whatever called it, AND IT IS ITS JOB WHAT TO DO
NEXT. Exactly the same as if you called /bin/mail and there was no
diskspace free - it's the script that called /bin/mail that needs to
figure out what to do next - not /bin/mail.

End of the day, it's always a chain-of-command issue. If your choice of
AV causes you headaches (due to it hanging/crashing/whatever), then Q-S
will be a problem to you - oh, and so will Amavis, Trend InterScan
VirusWall and whatever other system you use.
