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?
Please login to webmail and then send a email to the same address that you used to login at webmail. If the email arrives in your mailbox (webmail account) after a minute, then the mailsystem is working properly. In that casethe problem is either that postfix does not listen on all network interfaces or a firewall or router blocks port 25 outside of the server.
