Sorry if I missed this somewhere else, I'm having a bit of a brain fart thing today.
If I have the outside interface setup with multiple ip addresses (valid ones) and have the smtp proxy set to deliver to the internal IP address/mail server and the mail server set to relay to the internal IP of the astaro box, when it's delivered to the destination, which source IP address does it use from the outside interface?
When there is only 1 IP address bound to the outside interface, that's easy. When there are multiple outside IP addresses bound it will accept incoming on any of them, but does it always use the primary when going back out?
