mailscanner 3.15-3 proc dies without error/warning - tied to mailman?

If you run MailScanner with "Debug = 1" it will only do 1 pass of
and then stop.

As you are presumably normally running with "Debug = 0", check that the
"check_mailscanner" script works okay for you (it should print out the PID
if MailScanner is running, else it should start MailScanner up again).

Also, start MailScanner (using check_mailscanner) from the command line,
and leave that window open. You may get a Perl error message when it dies,
which for one reason or another may not be logged into syslogd.

Once you've got that error message out of it, I can investigate further.

What version of Perl are you using (perl -v).

Failing that, if you can give me login access to it (and the root pw) then
I will take a look for you.
