Outgoing IP for mail transport

Hallo,

is it possible to get the UTM to send emails from another ip than the first public?

Our PTR Record points to a ip where our Exchange can be reached from outside but this ip differs from the first public ip that the UTM is using for sending emails as a Smarthost.

It's not directly possible with Mail Protection, but you can use an SNAT masquerading rule for this.

Yes, that is right.

But there is a feature request for this and this idea includes your question:
SMTP: Multiple Hostnames/Interfaces Support
So you can vote for it [:)]

I voted, thanks for the hint [:)]

What should i set as source in the snat rule? I suppose that just set internal as source is not sufficient?

With you mean the public IP that should be used for SMTP out? Then this should be ok.
