I'm running postfix on an FC6 server and I'm having trouble receiving mail into the server... This is all part of a university project, btw.
Here is a graphic of the infrastruture I am using just to aid my explanation [img=http://img404.imageshack.us/img404/6370/helpmailqm2.th.jpg]
Basically, I can send out mail fine by relaying all the emails via my ISP's smtp server but any messages I send to, email@example.com
from an out address for instance, just get lost in cyber space.
Now, i obviously own the domain and have configured the MX records (provided by the company i bought the domain off) in many different variations to try and get mail to route to my mailserver. But, I have had no joy...
I believe the problem could be a number of things.
- The way I have configured the MX records using the domain name providers website is wrong and mail isn't routing correctly my external IP
- DNS needs to be configured on the mailserver? I haven't been able to do this as the main guide I have been following is Suse based and uses yast (which isn't bundled with FC). So I don't know how.
- firewall issue maybe?... but i doubt it.
If anybody could shed a bit of light on this for me or has any suggestions, I would be very grateful. Thanks.
