Is there a way for the different domains on a single SmarterMail server to send (SMTP protocol) from different LAN IP addresses? Naturally, the server is already configured with more than one IP address. If it is possible, I would like to know how to set this up. I can clearly receive email on different SM server IPs.

 

FYI the SM servers I have set up are on LANs and have LAN addresses; all port forwarding / NAT translation is done at the firewall (Sonicwall) level.
