procmail/postfix/tmda-filter
I'm trying to get tmda-filter working with procmail & postfix and
haven't had much luck to date.
According to the docs, I have to put a .forward file in place that
pipes to tmda-filter. I guess after that it gets piped into
procmail for further processing.
That's backwards to what I want. I don't want to bother
tmda-filtering anything that has X-Spam: Yes. No point.
From what I've been able to figure out, if I can dump error or
exitcodes to from procmail back to postfix, it (postfix) will
takes these emails as a temporarily undeliverable and hold it in
the queue.
I'm not sure what exit codes are where they might be found. I had
one person tell me that I could push back an EX_TEMPFAIL to
postfix to get it back in queue. But I don't know where these
come from.
Furthermore, I don't know if I can get an exitcode from
tmda-filter and push it back into procmail. I think if I can do
that, it would work OK, but procmail docs are....weird.
Is there some way that I can take the results of
:0w
| /usr/bin/tmda-filter
and push it back on the postfix email server?
