When you diagnose through exchange troubleshooting assistant you see an error saying virus found in email.


Worth checking to make sure its not the sonicwall

Issue was caused by Gateway Anti-virus on the sonicwall blocking outbound messages see fix below.

1. Login to the SonicWall

2. Security Services
