I've got a relatively new Courier server (0.37) on SuSE Linux 7.2 (kernel 2.4.4-4GB). Everything is working fine for around 200 users - imap, pop3, smtp, webmail apart from one thing. We're using shadow authentication.

I have two problems.

The first is with mail filtering. I want users to be able to set up out-of-office replies using webmail. They are currently able to set up filters, and the .mailfilter file appears in the user's home directory, and knowing what little I do of the cyntax, looks OK, but the file doesn't seem to be getting hit. I think I've checked all the stuff on the web site about setting up filtering...

/usr/lib/courier/etc/maildirfilterconfig contains

MAILDIRFILTER=../.mailfilter MAILDIR=./Maildir

and '/usr/lib/courier/etc/maildrop' contains

/usr/lib/courier/bin/maildrop

which looks consistent.

Finally, '/usr/lib/courier/etc/enablefiltering' contains

esmtp local

Can anyone offer any suggestings as to what I might have missed, or whether I shoudl look out for anything in the logs to say that maildrop has processed a particular message whilst delivery was being made?

Finally, (and I suspect this one is just me being thick!), misaddressed posts are getting bounced. I'd like to have them delivered to postmaster. Postmaster is set up in the /usr/lib/courier/etc/aliases/system directory, and I know my other aliases are getting processed correctly. Might I have missed a configuration flag somewhere in the setup perhaps?

TAI for any help received.
