Need assistance locating differences between Primary and Backup Mailservers - AV scan

[VTC]

Hey guys,

I need someone to help point me in the right direction.

I currently have a Primary Mail server the forwards inbox mail to our backup mail server.

Currently our primary mail server is receiving spam with attachments, and they are going to the users mailbox's, however the same message on the backup mail server is being flagged as virus content.

I need to find the area in which this maybe happening so I can replicate it from the backup mail store to the primary mail store.

Anyone?

Both Mailservers are running 6.0.5.
