Outgoing email is using the default gateway IP instead of mail server's configured IP

Brent Baucom

Just started using Email Protection feature and it's working great for the most part.

 

However, apparently our main NAT ip address is on a block list and for some reason outgoing mail is using that IP address instead of the separate address configured for the mail server.

 

Anybody have an idea what could be causing this?


Thanks.

    Solutions from Sophos : 

    Create new SNAT rule to route email traffic out correct interface

     

    Traffic from: WAN interface 

    Using service: Email Messaging

    Going to: Internet IPv4

     

    Action :

    change source to : WAN (exchange server) Interface

     

    Support was very friendly and helpful in resolving this matter.
