N-W, I stand corrected. I should have indeed said that the PTR record needs to be updated, not the MX one.

Hello Experts!<br />
<br />
I have a working NSA2400 with failover (ATT &amp;&nbsp;Comcast). <br />
<br />
All my inbound mail flows via ATT (X1) and outbound via Comcast (X5). I would like to have outbound mail also flow via (X1) instead of going through the other NAT on X5.<br />
<br />
How can that be adjusted?<br />
<br />
Thanks much!<br />

SonicWall NAT

Hardware-based firewalls provide more sophisticated protection for inbound and outbound traffic than the simple Windows software firewall or the basic NAT firewalls found in routers. These devices implement techniques such as stateful packet inspection, deep packet inspection, and content filtering; and may include built-in antivirus and anti-malware protection.
