Hello, I followed the "Perfect Setup Debian 3.1 sarge with ISP" tutorial to the dot..., and everything installed fine. I installed ISPConfig, worked fine, but e-mails dont. Heres my server information: hostname - server1 domain - hotkeyproductions.com ip - 22.214.171.124 ns1.hotkeyproductions.com ns2.hotkeyproductions.com (I have my domain named registered with godaddy.com, and i followed the GoDaddy/DNS tutorial also posted on the site) Now, I can log-into my webmail, via the webmail upgrade, or thunderbird and it says "E-mail Sent" but it never reaches the address. I've been testing it by sending it to my hotmail account, Now if i send one to email@example.com, hotmail also says its sent, and returns no error's, but it never gets there, my inbox is always empty? Any help would be amazing, Thank you.
