We generally discuss SpamAssassin and its development via the following mailing lists. Where available, there is a graph which shows you how much mail you should expect to hit your inbox if you subscribe.
For announcements of new versions of SpamAssassin.
Subscription: send mail to announce-subscribe -at- spamassassin.apache.org
A general user list. Please post your questions to this list. Developers and members of the PMC monitor this list and answer questions as time permits. You must be subscribed to the list with the email address you use to post to it.
Note: before you submit a question to the mailing list, please thoroughly read the FrequentlyAskedQuestions list and other info on the FrontPage, as your question is likely already answered there. If you've looked carefully but still can't find your answer, then go ahead and post -- but be sure to note
what version of SpamAssassin you're using, and
Please don't ask questions about versions older than 3.3.0, as you don't want to use an old version for the same reason you wouldn't use an out-of-date anti-virus scanner.
This list has high enough volume that you will want to filter it to a separate folder so it doesn't fill up your inbox. This is a basic function of email clients, check your mail client's documentation for instructions. If possible, it is best to filter on the header List-Id: <users.spamassassin.apache.org>
