SpamAssassin 2010 bug issue

As some of you may know by now there is an issue with SpamAssassin scoring for all emails sent as of 2010. The bug causes an extra 3.4 point addition to your overall score. It is a particularly high scoring rule considering that the default threshold is 5.0.

A fix to this issue has been made available, but it may take some time for servers running SpamAssassin to make the necessary updates.Any emails sent as of January 1, 2010 to servers running SpamAssassin before the fix was made available, and to any servers running SpamAssassin that have not implemented the fix, will experience a higher than normal SpamAssassin score. This might impact delivery for messages where the score increase is significant enough to put the email's score above a filtering threshold.

If you are using a set of tools to test your messages before sending them out, such as StrongDelivery Tools, please make sure that your team is aware of this issue if it arises
