Mike,

The changes for the versions above 2.6.3.487 are reported below. Nothing *in theory* should have affected the way SpamFilter communicates with your SMTP server. If you can please forward us SpamFilter's activity log for a day this happens (or the section of the log with the relevant info), we'll try to see what happens. Please also let us know what the email addresses involved are, so we can find them in the logs. Also, are the "syntax error messages" actual bounce emails that are sent, or simply entries in the SpamFilter's log?
