When upgrading to SpamAssassin 3.2.x, it is essential that you read the SpamAssassin 3.2.x 'UPGRADE' file. Also, please read the Release Announcement to check out all the new features.
If you run into any problems, or some functionality appears to stop working, read that file (again). If it's not dealt with there, check FrequentlyAskedQuestions – especially the Installation and configuration... section.
