First off apologies, I'm from a medical background not a networking one, but I've got roped into setting up a windows 2008 server.
So far web server running, fixed IP address assigned (within a large private network of the National Health Service in the UK if that makes any difference) and the network team have assigned a DNS entry for me which works, so the server can be addressed as nww.myserver.nhs.uk
I've only got ports open on the router for 80 and 443 (http and https) at the moment, so presume I need a different port to enable email services.
My need is to be able to accept an email to the domain name like email@example.com in order to pick up a confirmation mail from an SSL issuer (Comodo) I guess to confirm that I control the domain.
After that I don't actually need mail services on the server.
I see lots of stuff about setting up SMTP services but thought that was about mail out and re-routing, but how do you get the server to "listen" for mail to the domain (assuming I open port xyz or whatever it is) ?
