Quoting the man page:

DISPOSITION
       mimedefang.pl examines each part of the MIME message  is  examined  and
       chooses  a  disposition.   Unless otherwise indicated, the dispositions
       should be called only from filter and not filter_begin or filter_end.


so why call it from filter_multipart() and not filter_begin() or
filter()?  Don't you want to accept the message atomically and
stop further filtering of it?  I.e. short-circuit the testing...

Can anyone think of any other methods to detect messages queued
locally rather than accepted over a socket?  I.e. messages read
from stdin?

Also, I tried to look at $SendmailMacros{'daemon_name'} but that
never seems to be set.  Ditto for daemon_flags.
