This is an old bug, but it seems to be still happen with Courier 0.65.0-1.
Any idea why this does happen?
The only way I could reproduce it is with a device-full error. In
that case I get the following from the script attached.
1578-north:mdt$ . ../../../mdt.sh
-rw-r--r-- 1 ale staff 212595 2010-10-22 18:11 logtest
maildrop: Changing to /home/ale/tmp/mdt/foo/mdt
Message start at 0 bytes, envelope sender=ale
maildrop: Attempting .mailfilter
maildrop exit code: 0
-rw-r--r-- 1 ale staff 212740 2010-10-22 18:12 logtest
1578-north:mdt$ . ../../../mdt.sh
-rw-r--r-- 1 ale staff 212740 2010-10-22 18:12 logtest
maildrop: Changing to /home/ale/tmp/mdt/foo/mdt
Message start at 0 bytes, envelope sender=ale
maildrop: Attempting .mailfilter
maildrop: ./Maildir: No space left on device
maildrop exit code: 75

IMHO, what happens is that Postfix doesn't know whether it was the
logfile or the message that couldn't be written, hence it tries again,
and again, and...
