Emails are getting stuck at the Fortinet FW. Our email server shows this log:
no mail sent during session from [10.10.125.254] <-- that is Fortinets IP address.
For emails server we have an Exchange and a Linux box behind the Fortinet.
so Firtinet --> 1. Exchange 2. Linux
Fortinet is new to me, but I am experienced with email.. Seems that emails are getting stuck but I don't know where to check.
