Mail not being delivered
I have an issue and I don't know where it lies. I have sendmail 8.12 running fully configured to send and receive mail. I have registered an MX record for my domain which points to my server. It is able to send mail out of the server to anywhere on the net, and also able to transfer mail on my local network, but when mail is sent externally to my local domain nothing is received. Neither do I get a returned email giving me a failure. Its like it dissapears completely off the face of the earth.
Is this a configuration problem with my sendmail server or something to do with how my MX record is setup ?
