Hi, I've got Imail running behind a Coyote Linux Firewall doing NAT and port forwarding. This forwards port 25 on to the imail box. Everything works fine
I have selected "No relay" on the smtp services security tab. If I send mail from a host on the local network (10.x.x.x/255.255.0.0) then they have to authenticate or they don't send - so far so good. When I use a mail client (such outlook express) on a pc dialled in to my ISP then I can send with no authentication. Interestingl, if I telnet to the server I get no joy unless I use a local user ID. If I run the open relay tools at abuse.net it passes all tests and reports that its not a relay. I'm guessing that this is related to the port forwarding - the Imail server is seeing the inbound (from outside) smtp stuff as originating from itself and so is sending it??? So on to my question - how secure am I? and what can I do to get it to behave as I want to - ie anyone that sends has to authenticate?
