Hi
I'm a newbie. I'm replacing a Smoothwall firewall with Sophos UTM software. I'm much impressed with Sophos software, although it is tricky to get stuff working and getting my head round it as it is all so different to Smoothwall (and much nicer)
I have my webites all working fine, with SSL redirect
I want email protection now
My setup
3 NICs. Internet. Green. DMZ. Webservers and email are on DMZ. I have fixed IPs, but the ISP can change the router IP (Sophos is doing the routing)
UTM has it's own outward facing IP. It has 2 additional outward facing IPs for my 2 websites. One of these IP's is also my mail server. Internally the mail server is on 192.168.1.11
My mail server is MDaemon. I have it set to use 192.168.1.1 as it's smarthost (I guess, so that outbound email goes through Sophos)
I can send out e-mail okay, and in the Sophos email log I can see it is working. However inbound email is rejected with a "relay is not permitted" error in the log. For the moment then I have setup a DNAT so port 25 gets around the email protection, so I can now get e-mail but it isn't scanned
It's obviously something silly. Any ideas?
