Lion Server and Mail
Page 1
Of those here who have experience with Lion Server and configuring mail, can anyone tell me why my server would allow me to send mail but not receive any? After configuring my server for various services, most everything is working quite nicely, but mail isn't one of them. DNS seems to be working fine; I checked the domain's MX record, and it's good as well. So... any ideas as to what might be causing this?

It could be your ISP blocking port 80 or you don't have MX records on your server so it knows how to route it. I did a tutorial on it on Youtube that might help (though mail servers can be tricky): http://youtu.be/QoyevsjK8rE. Hope that helps.

MX record seems to be fine. ISP isn't blocking port 80, but it may be blocking port 25 and 143. I have to check. Nmap scan shows 25 and 143 opened on the local IP, but not via WAN or FQDN.

you'd have to use a proxy or secondary connection on an external IP (to your ISP) to see whether you're blocked on port 25/143. AT&T blocks it, as does Verizon, IIRC. If this is your problem, you'll need to go through a hosted proxy to receive external mail, or pony up for a business account, or change to an ISP that doesn't block.
