Hello
I have exchange server 2013 and I'm running XG106 (SFOS 18.0.4 MR-4 in MTA mode,
everything's was working fine for more than one year yesterday we stop receiving emails ,no configurations changed on Sophos or server.
I checked up the Sophos mail spool I found all the incoming emails are stuck in the email spool with failed status, and in the log viewer its shows all incoming emails
with (Email has been accepted by Device and queued for scanning) message.
any suggestion please
