Throughout my installation, I followed the "How-To" for a perfect server set up for ISPconfig3. One of the problems that i've been having though is that when I set up an e-mail account, i can get into it and send e-mails correctly, but I can't receive any. I've googled this for a couple hours, and I've tried changing settings for about a week. My server is set up under DMZ on my router, and everything else works, however, I can't figure out why my server won't receive any e-mails. Anyone have any ideas?
