Greetings. I have a question that *seems* like it should be intuitive
enough to answer, but I'm having trouble wrapping my brain around it.
I'm using qmail, procmail, and tmda 0.67.
My .qmail file pipes mail to 'procmail -p'. I'd like to call tmda-filter
from procmailrc. If tmda-filter decides to do anything with the message
other than approve it (e.g. send a confirmation, drop, bounce, etc), then
procmail shouldn't have any more work to do in that run.
However, if tmda-filter approves the message (e.g. it passes the filter),
I'd like procmail to keep working with it.
The procmail file I'm hoping for looks something like this (in
pseudo-recipe terms):
1) pass and sort known mailing list messages
-if a match is found, message is filed and process ends
-otherwise, keep going to next recipe
2) Message is to an address we don't usually want to filter, but looks
like spam
-pass to tmda-filter
-if tmda-filter does something (confirm,bounce,drop), process ends
-otherwise (message is confirmed), keep going to next recipe
3) pass and sort mail with other particular headers
-if a match is found, message is filed and process ends
-otherwise, keep going to next recipe
4) pass message to tmda-filter
-if tmda-filter does something (confirm, bounce, drop), process ends
-otherwise (message is confirmed) keep going to next recipe
5) if message is destined for my cell phone, route to cell phone
6) default delivery
A few notes: hopefully I've made obvious the kinds of weird things I want
to do: if someone sends a message to
"[EMAIL PROTECTED]", an address I don't normally want to
filter or do confirms on, but looks like spam (because, say, it has an
RBLcheck header in it that I can detect with procmail), then I want to
have TMDA confirm it. Likewise, if a message is sent to my cell phone
address (which is routed to procmail via .qmail files), I want to make
sure it's confirmed by TMDA before it gets passed to the phone, but I want
to do that particular routing in procmail. The end result is that I can
pass mail sent to a variety of addresses through the same filtering
system, but treat each one a little differently.
I guess the theme is that TMDA and procmail both have similar kinds of
filtering options, and I'm just more used to procmail's, and want to work
with it for everything except the whitelist/blacklist stuff. So I
basically want to treat tmda-filter as a filter that will fail/defer
(confirm,bounce,drop) or succeed (pass the message through).
Am I thinking about this the right way? Is it painfully obvious how this
should work, or am I trying to stretch TMDA in directions it's not
supposed to go?
Thanks for any help.
Chris
