Hello!
I want to build a mail server on my PC. So I opened ports 25,110,143 and 443 in both Windows firewall and in my D-Link NAT router.But for some reason when I check the ports,they appear to be closed (I use online free port status check services).I called my ISP and they told me that they don't block anything...So where could be the problem?

yes,it's interesting...BEFORE I tried to open all those ports they appeared as "stealth" in Shields UP and after I tried to open them-they appear as "closed".So it indicates that they are actually OPEN,but only appear as closed since there's no service in my PC that utilizes them? So should I go ahead and install mail server software to make sure or what? I don't know how to use a program that listens to those ports.I thought about Outlook Express..but it didn't make any difference.

A configured mail server would use those ports.  Outlook Express is a mail client, not a server.

so is it different when mail client uses port 25 or a mail server does in the context of my question?
right now I'm installing hMailServer,so...we'll see what happens...

OK...it works in Shields UP!!!
I'm logged in as an administrator in hMail Server,so now I see that ports 80,25,443,110 and 143 are OPEN.
