Aaron, Gary, | 1. internal user x sends mail to external user y. | 2. since we are sending mail to user y, user y must be ok to receive | mail from. | 3. amavis or SA sees that we are sending mail "to" person y and | automatically adds user y to whitelist, either per recipient or global, | for future incoming emails "from" user y.

I see, I misunderstood. Opening up a reverse channel indeed sounds like a good idea, if done for a limited time and if opened just for the sender/recipient pair, and contributing just a couple of negative score points (not hard-whitelisting) to the final spam score. SQL-based soft-whitelisting mechanism could probably be used for the job. It is up to some external mechanism to add sender/recipient pairs to a soft-whitelisting database, and to expire them after a couple of days, preferably slowly reducing negative score towards zero in few steps or taking elapsed time in score calculation. Information about outgoing sender/recip pairs could be collected from reporting/logging SQL database, it is not necessary to parse the log file. Contributions welcome.
