Hi,

We recently migrated from Microsoft Exchange 5.5 SP4 to Microsoft Exchange 2003 SP2.

Ever since we turned off our Exchange 5.5 server, last week, Spambayes 1.04 on our Microsoft Outlook 2000 clients (sp3) has for some clients stopped filtering emails and for some clients will filter emails after a few spam messages are selected as "Delete As Spam".

It seems as though Spambayes is having issue with the change from Exchange 2003 from Exchange 5.5.

What has changed in our configuration that maybe causing this?

We've tried several different things to try and fix the issue with no success.

We have done the following:

Restarted the pc's

Restared outlook

Reinstalled Spambayes 1.04

Left messages in the Junk E-mail folder (to help with history)

We've gone through SourceForge and we did not find a situation similar to ours.

But none of the changes above have made any affect on the performance of Spambayes. Any suggestions or insight would be much appreciated.

Thanks,

Kamran
