SMTP: Multiple Hostnames/Interfaces Support
With the SMTP proxy able to handle mail for many domains, allow the proxy to be configured so that an admin can assign a hostname per profile, or have the proxy report different hostnames per outgoing interface. (and the ability to specify which domains/profiles go out which interface). Allows for easier management and adoption of many smtp domains on a single asg appliance.

Hey guys at Sophos, it's more than ten years old request and this would be very useful - so please implement it.
Almost 10 Years and it's still not here. Any plan on having this implemented some time?

This is really needed in multi wan connection szenarios and failover.
At least it should be possible to assign the smtp service to different interface ips using different mx hostnames to support wan failover using multiple mx records.
Tim Schönwald commented
This idea is 8 (!) years old and has 337 votes by now. It's obvious that Sophos has no plans on implementing it.
Listening to customers was definitely much more important back in the "good ol' Astaro times"...
Was just about to create this request myself. With multiple uplinks for email redundancy, only one hostname per domain causes failed rDNS/DNS consistency checks for the redundant uplinks.

In the end I've created a DNAT assigned to the external IPs I dont want listening to SMTP so they goto an non-existent internal IP address. Pen-test reran and fine now.
Rob D commented
Just had a pen test and highlighted SMTP being listened too on all external IPs, please fix this
Steffen Hornung commented
Even with a simple helo lookup check you could get denied because UTM currently has only one static mailserver name it sends out, if you have natting setup to distribute different domains through different IPs, so it is rather useless to set it up when this is not possible.
We also Need this feature

I also Need this feature

I cant believe this is even a feature request. This is ridiculous that the STMP Proxy listens on all addresses the firewall arp's for. This is making my pen test scans look awful.
Doug Clow commented
Needed because RDNS is used to filter spam by some mail servers
Please, please, please please!!!!
Yes, this is an essential functionality which is muched needed by us. Please implement it. Thanks.
I just want to echo everyone else below, this really is a much needed feature. I am new to Sophos and have only been using it for about 3 months now, but I can't believe such a basic function is missing and I'm surprised that nothing has been done since this has been a topic for 6 years.

This feature has been requested for years now - when can we get that working?
Rolf Müller commented
Hey Sophos People, the request for better smtp implementation has been around for years now. It would be nice if you could improve this, please!
Mike Horwath commented
I'll agree with the DKIM issues, and policies per domain.
I don't agree with the binding to a different address per domain as there is no need - you can handle hundreds of thousands (millions!) of domains for email over any individual IP address.
Same with outbound, and if you keep a clean house then any worries about later RBL issues are zero.

I was disappointed, when I realized, than angry as this is really needed, and finally furious because it can be set-up on any handmade linux box... Really, come on... For that money? Such elementar feature missing?
realy need, would be awesome.
