Hi, I hope someone can help me with a "Perfect Setup - Ubuntu 6.06 LTS Server"! I have successfully completed the how to and have the system running and I have logged into ISPConfig. I also installed WebMin, all seems fine there. But no matter how many times I read the manual and set up accounts I cannot get the mail to work! I setup the details for a site and one mail account ([email protected]) for the domain I have the server setup for via ISPC then my mail client Thunderbird. I send an e-mail from my web based Yahoo account to the new account on my server all goes well, no returned mail and I can connect with Thunderbird, but it says there are no new messages. Each time I send a test message, the servers H.D.D. light flashes (just like the windows mail server I have had running for a couple of years now, XP with MailEnable), but no mail! I know the D.N.S. records are ok as my current mail server works, I use ZoneEdit and I change the port-forward on my router to the new servers I.P. when testing. I have re-installed everything many times with slight variations to try and figure it out and I have trawled the web and these forums , but so far nothing I have found has worked for me. I'm on a static I.P. behind a NAT firewall that I am comfortable configuring, I have the domain pointing at ZoneEdit and then to my static I.P. The server is an old Dell Optiplex GX1, CPU 450mhz,R.A.M. 128mb, H.D.D. 14gb, ISPConfig v2.2.21, WebMin v1.400. The site works, I can view it using http://freeproxyserver.net and I can WebFTP and FTP using a client. Someone commented (http://www.howtoforge.com/perfect_setup_ubuntu_6.06_p4#comment-3068) that the hostname should be set to 'server1.example.com' as opposed to just 'server1'. I have tried both ways with no success, which way should it be? I also wondered; 1) Should all the I.P's in the local system be local I.P's. Should there ever be the external I.P. entered anywhere? 2 Do I need to check the D.N.S. box's, particularly the DNS-MX one when creating a mail account? I haven't. 3 Does this setup need it's own D.N.S. server at all? Any ideas/help would be very much appreciated! Sorry if this is supposed to be in the ISPConfig forum, I wasn't sure.
