- you need to maintain a database containing every address you ever received mail from and have sent mail to. All addresses must be recorded as you receive mail from them and updated to record when you send mail to them. You could delete addresses that you haven't replied to for, say, a month but that is about all you can delete. - marking first-time messages as spam won't work for a business and probably won't work for a private mail user. - this doesn't work at all for mailing lists that get spammed from time to time, especially if the spam comes from an online forum (hint: the same sender address tends to be used for all forum posters). How do I know? I run a mail archiving system which provides exactly this service (automatic whitelisting of addresses I've sent mail to) to my copy of SA via a plug-in. The points I listed reflect my experience. Martin
