As per the mimedefang-filter man page:

which no one seemed to dispute, so I took that to mean that it was safe, if
somewhat inadvisable, to call stream_by_recipient() from filter_end().
The documentation of stream_by_recipient() is a little thin, in particular the
return value, and whether one needs to call action_discard() to avoid duplicate
delivery, or if it takes care of that for you (which would seem not to be the
case, at least in my usage).

It if makes you feel any better, I have been calling it from filter_end
for quite some time now. And, yes, I wrap the method with an if
statement that then discards the mail. This is also something I use for
required logic earlier in my filtering:
#***********************************************************************
# %PROCEDURE: will_stream_by_recipient
# %ARGUMENTS:
# %RETURNS:
# True when streaming will take place
# %DESCRIPTION:
# Determines whether or not this message will be streamed.
#***********************************************************************
sub will_stream_by_recipient() {
return 0 if (!in_message_context("stream_by_recipient"));
if ($#Recipients <= 0) {
# Only one recipient (or none??)
return 0;
}
return 1;
}

Nate
