I narrowed it down.. took me half the day. I have debian systems where
it works and others where it doesnt. Same (relevant) packages etc.
Stracing, trying comparing etc finally led me to the culprit:
razor (2.85 here)
and only if you have
logfile = sys-syslog
configured in /etc/razor/razor-agent.conf (on debian at least).

Without looking at the code, since my eyes are about to finally freak
out now, i guess you integrate the razor perl modules directly in
MailScanner which then initialize/openlog the Syslog again and mess it
up.

Maybe someone else wants to verify this on a non debian system too, but
i'm quite confident that this is the cause for the behaviour.
