Greetings, I have been trying to get postfix, maildrop and courier-imap to work together (using virtual domains & users) according to the MAILDROP_README.html [1] on postfix.org but with no luck so far. I am trying to make use of user+extension@domain style addresses (but even without extensions mail is not getting through). Without maildrop, everything works fine.

I am at a bit of a loss as to what the problem is, and couldn't find any direction in the list archive so any help is very much appreciated :-)

The error log (mail.log) says: Jul 31 15:03:50 dumbledore postfix/master[14291]: daemon started -- version 2.1.5 Jul 31 15:03:50 dumbledore postfix/qmgr[14296]: 77DCE20D6: from=<us...@example.com.au>, size=570, nrcpt=1 (queue active) Jul 31 15:03:50 dumbledore postfix/pipe[14298]: 77DCE20D6: to=<user+ex...@example.com.au>, relay=maildrop, delay=1127, status=deferred (temporary failure. Command out put: /usr/bin/maildrop: Invalid user specified. )

Obviously "user+ex...@example.com.au" is an unknown user but addresses without an extension (eg "us...@example.com.au") also fail.

I am using: courier-imap 3.0.8-4 postfix 2.1.5-9 maildrop 1.5.3-1.1

Thanks, Brett
