How To Report A Bug In SpamAssassin
First, make sure it really is a bug; it might make sense to ask on the "users" mailing list first (see MailingLists).
Report bugs on our bugzilla at http://issues.apache.org/SpamAssassin/ .
If you are reporting an error in how particular mails are processed, or the behaviour of specific rules, please attach sample messages to the bug report. Do not cut and paste them into the 'Description' field. This causes them to be corrupted, and there's a good chance that certain key elements of the formatting will be discarded.

If you can, test with "spamassassin -t < message.txt" and ensure that reproduces the problem.unmigrated-wiki-markup
