Exim4 integration?

[Mandarb]

Is anyone using exim4 with spamgourmet? I am trying to set up a personal site and have most of it working (more questions in another post), but I'm not sure how to integrate it with exim4.

Do I forward all emails through spamgourmet? What happens to local deliveries (i.e. myuser@mydomain.com)?

Thanks,
Omen

It should work with exim, but we've never tested it. The trick is to forward all email for a particular domain to the spamgourmet code. If you only have the one domain, you can either use the "unix accounts" spamgourmet configuration (not tested for a long time), or explicitly deliver mail to local accounts prior to sending all mail to the spamgourmet code.

Okay, here is what I have done so far to get spamgourmet to work with exim4 (Debian unstable). I am using the split config files option so I had to add two new exim4 config files and a small patch to spameater.pl. The patch is required because exim4 does not put angle brackets around the for in the received headers.

Then run

sudo update-exim4.conf; sudo /etc/init.d/exim4 restart

and you should be all set.

The reason I use two transports and two pipes is to make a backup copy of every email in /var/mail/spamgourmet before it gets delivered to spameater.pl. This is just for debug purposes.

I do not have a special domain for spamgourmet, so I had to find a way for exim4 to realize which emails should be routed to spameater.pl. I did this with

Code: Select all

  local_part_prefix = *. : *~ : +*+*+

It is a little crude (any email address with a . or a ~ in it, or any address that has 3 pluses) but it seems to work.
