Folks,
I've just been playing with setting up a SA config with exim (theres
probably going to be a SA HOWTO added to the exim web site once a few of
us get some text written).
There are 2 things that I think would make the integration a little
easier:-
1. The ability to push a BSMTP stream into spamc, and have
a BSMTP stream come out of it. This makes transporting
the addresses (envelope sender, envelope recipients) much
easier and resilient to the worst excesses of shell
expansion and/or command line length limitations. This
could be really good for a large scale system that pushes
all incoming mail through a SA filter.
Original idea was to have spamc de-encapsulate the message,
passing the BSMTP straight through without touching it
pushing the DATA content up to spamd, putting the returned
content out followed by the BSMTP trailer.
An alternative might be to pass the whole transaction up
to spamd (with appropriate flagging), which might give
spamd a chance to make decisions based on groups of recipients
etc. Theoretically it would also be possible to have it
handle multiple user requirements, but thats going to be
*really* hard when you are working with a single message
to multiple recipients.
2. The ability to pass a destination program and arguments
to spamc and have it fork/exec that. This is another
wish to bypass shell command line tampering. Its a minor
requirement, but could have its uses.
I'm thinking about implementing both of these here, but would be
interested in comments, or if people are doing stuff in parallel to
this.
I'm also considering the idea of a direct hook into the exim 4
(experimental) filter hooks.
Nigel.
