So, we wouldn't be able to unlearn historical emails (processed before the upgrade), but there'd be few other side-effects?
Or am I missing something? Phil -----Original Message----- From: Kevin A.

I believe we should recommend restarting the bayes database with 3.4.0 and I've added notes to the proposed announcement to that end as follows: Important Bayes Change ---------------------- Beyond the ability to use redis as a Bayes backend server, Bug 5185 changed the way that message IDs were calculated for emails. Because of this change, you can't unlearn a message if you upgrade from 3.3.X to 3.4.0 and you might learn emails twice. It is likely best to clear your Bayes store and start from scratch to avoid any issues. Thoughts?
