Server with multiple IPs, how to bind SMTP out to a specific IP?

My Axigen server has two IP addresses. Let’s call them IP A and IP B. When it sends email out, it is sending via IP A, but I want it to send via IP B. I can’t find any configuration option allowing me to specify which IP address to use when sending email. Am I missing something? How would this be configured?

Thanks!

Hello,

You should create an advanced SMTP rule to relay all the messages through IP B from Webadmin -> Security & Filtering -> Acceptance & Routing -> Advanced Settings.

The condition section will be empty to match all messages and in the action section select “Use Interface” available in “Relay” group and enter IP B
