The best place to ask further questions that aren't already answered here is the SpamAssassin 'users' mailing list. Subscription details, and the list posting address, can be found at MailingLists.
You will probably be asked to describe your email infrastructure (which MTA you use, and how SA is "glued" onto it) and to provide sample message(s) that illustrate the problem.
If you have a sample message that illustrates a problem, don't send it directly to the list. Instead, upload the complete message (including all headers) to a public file hosting service like pastebin, and include the URL for that in your message to the list. It's okay to make small changes to the message headers to preserve the privacy of the recipient or to hide details of your internal network layout, but if those changes may affect analysis of the cause of the problem you may be asked to provide an unmodified copy of the message to the SA team in private.
Please read FrequentlyAskedQuestions before posting! If you ask a FAQ, it's very likely nobody will answer your mail.
