Hello,
looking in the archive there are multiple question like "howto access
the queueid from pipe service"
(http://marc.info/?l=postfix-users&s=pipe+queueid)
I had the same problem some times ago and wrote a patch.
Now I have the possibility to use the pipe command in master.cf like
described in
http://www.postfix.org/FILTER_README.html#simple_filter
filter unix - n n - 10 pipe
flags=Rq user=filter null_sender=
argv=/path/to/script -q ${queue_id} -f ${sender} -- ${recipient}
inside /path/to/script I could access the queueid (for logging
purposes) like other daemon usually do also.
That make the logging more precise when messages are delivered to a filter.
Maybe the patch could included in future versions of postfix.
Andreas
