It looks like Exchange finally got the features that SpamAssassin, Amavis/amavisd-new and Postfix have had for some time: connection blocking by IP, RBL support, spam ‘scoring’, multi-level actions on spam, reject messages for invaild recipients, etc. The recommended email infrastructure even looks like what most people running Exchange have now with a bridgehead doing tagging/blocking. The main thing is you could now switch to having Exchange out there, if you so choose.

There’s a fairly interesting Birds of a Feather session at 7pm on small IT shops, might head on down there.
