Here's what we do. If I send mail to [EMAIL PROTECTED], my exim drops an entry in a database ([EMAIL PROTECTED], [EMAIL PROTECTED]). Any mail from [EMAIL PROTECTED] to [EMAIL PROTECTED] is whitelisted on the basis that we've already swapped mails, and so doesn't go through out spam filters. I thought this would be more effective than it is, but when it comes down to it, only about 1.2% of inbound mail gets matched by this one (bad time of year to get statistics though - we have lots of new users at the start of the academic year, so the numbers won't stabilise for a few weeks). 25% of mail going through SpamAssassin (after our greylist) comes out as spam, so it's currently saving 1.6% of our SpamAssassin load. Not a massive saving, but it's a very simple, quick test and is very unlikely to let spam through and, depending on your user profile, could be much more effective. You could take it a lot further and allow [EMAIL PROTECTED] to e-mail any [EMAIL PROTECTED] on the basis that someone here has mailed him. I choose not to do that, but it might up the percentages significantly.
