I still virus check outbound mail via MailScanner so same result, just different implementation. I just didn't want to run amavis AND MailScanner...seems like a waste of RAM.

Adopting this approach allows the AS break out from Zimbra into MailScanner while still allowing your users to train Spam/Ham. This all provides a double whammy due to if you introduce additional mailstores and MTA in the future, using Zimbra, they can all share a common bayes.
Yep - did that :) Exported the Zimbra bayes/awl then once it was set up in the new SA on SQL, did a simple import. The result:
... dbg: bayes: corpus size: nspam = 4607, nham = 22069
Quiet server for home, so not a massive volume, but it is a test bed for some of the systems I maintain ;) Always nice when I can write off tax on test systems I use myself.
