I am am also able to telnet my domain name port 25 but I am still unable to send out mail.please can someone suggest anything lol i been at this for 2 days.( am not sure if the setup allows you to have one NIC,I've been using exchange for sometime now and this is my first time setting it up with one NIC.
Please Help

You need static IP and PTR record for your MX, othervise you will be blacklisted. Using dinamic IP for e-mail server is only improvisation and you will have many problems. If you do not have knowledge and experiance for administering mail server you can host your domain and acounts on some provider servers. You can find many providers searching on google selling this service, but I am recomending you to chose someone in your neigburhood. Good luck. |
