Hi,

We've intentionally introduced a mail loop within a maildrop filter file. The logs show that the message has been bounced, but the bounce message doesn't seem to go anywhere.

The log shows this: Aug 26 13:01:24 stoat postfix/pickup[14030]: 99AD5A4037: uid=1510 from=<> Aug 26 13:01:24 stoat postfix/cleanup[22073]: 99AD5A4037: message-id=<4a04...@mail.gmail.com> Aug 26 13:01:24 stoat postfix/qmgr[14027]: 99AD5A4037: from=<>, size=3471, nrcpt=1 (queue active) Aug 26 13:01:24 stoat postfix/pipe[14717]: 99AD5A4037: to=<de...@DOMAIN.net>, orig_to=<dev2...@DOMAIN.net>, relay=maildrop, delay=0.22, delays=0.16/0/0/0.06, dsn=5.4.6, status=bounced (mail forwarding loop for de...@DOMAIN.net) Aug 26 13:01:24 stoat postfix/qmgr[14027]: 99AD5A4037: removed

The pipe to maildrop in master.cf of my postfix config is: maildrop unix - n n - - pipe flags=DRhu user=vmail argv=/usr/bin/maildrop -d ${recipient} ${nexthop} ${user} ${sender} -a -V2 /etc/maildroprc

I'm running maildrop 2.0.4 and postfix 2.5.1 on Ubuntu 8.04. Do I need to explicitly list the sender with the -f option when piping to maildrop or is there likely some other problem with my config?
