SpamAssassin (or other spam filtering) before forwarders

Bump.

I would welcome a solution too, but still no answer to this topic.

 

Yes, the Exim REJECT ACLs operate at a server level and you cannot say "reject with a score greater than 20 if destined for domain A, reject with score greater than 20 if destined for domain B."

You can spam-filter forwarders by doing the following:

1. Add a POP3 account for each forwarder
2. Set up a filter on that POP3 account to discard any mail with a spam score greater than xx
3. Set up the forwarder

Then and only then will spamassassin filter the incoming mail before forwarding it on.

Wouldn't this fill up the pop3 account?

 

Yep, it very well could. You need to make arrangements to clear out that mailbox at some point or set up a cronjob to delete the contents of that mail folder every so often. You might actually be able to go into the POP3 mail account, set it to /dev/null all incoming mail and it _may_ still forward that email - i forget and do not have the time to check.

Forwarding is a bad idea anyway if the mail system you are forwarding to scrutinizes incoming messages and rejects them if they are spammy. AOL, Comcast, and a lot of other places do - and it causes problems.
