We just followed Google's instructions to migrate from Postini to the regular Google Apps, which supposedly has built-in email filtering.

I'm not impressed.  My inboxes are now flooded with emails about penis pills, kenyan brides, and rolex watches.  I know Google's help files say that I should start marking these as spam in my gmail interface.  But Postini seemed to be able to catch these automatically.  Do I really need to go in and teach the Google Apps email filters every bad sender, everything that should be added to "objectionable content", etc?  The beauty of Postini was that it figured this out automatically -- sure there were some false positives that got caught, but you'd see them in your daily report and deliver them.  Now I get 20+ emails a night with this garbage.

I want my postini back.  Or am I missing something in my settings?
