We are moving to Postfix with PolicyD (http://www.policyd.org) to solve this exact problem. PolicyD lets you limit the total number of emails sent per user per day. No reason a normal home user should be sending 1000 messages per day and this will let us limit it. There may be a plugin for Courier that does the same thing.
There is still the issue of people flagging the jokes between friends and church newsletters as spam instead of deleting... Some larger mail shops run all their outbound email through a spam filter to stop outbound stuff. If the spam is coming from a botnet there is a chance the spam signature is already in the spam filter database. I know some people use SpamAssassian for this.
