configure email server


I have Redhat Linux 9 and one of those dynamic domain names (blahblah.no-ip.com) and I want to receive emails at this domain (someuser@blahblah.no-ip.com). I can send email out (outside the system) and the email indeed says from: someuser@blahblah.no-ip.com, but when I send email to someuser@blahblah.no-ip.com it doesn't reach (and i get undeliverable error message).

how do i fix this?

TIA

You need to assign your MX record to that DNS. Also, something simple, is to see if you can even ping or nslookup that DNS from the outside world.

does your no-ip.com-account support a mailserver ?
it is not a standard feature, but an option.

OK, you are going to have to be more humble from now on, because you are so ignorant you don't even know how sad it looks. Shutup and listen.

For email servers you need to have your DNS record set with the proper MX record point to your DNS. Mail will not now or ever route to your mail server simply because you started postfix on your box.

The internet does not give one shit about your mail server. You need to put the entry into the DNS MX record for anyone to know that you ever existed. And dynamic DNS services do not do this by default. You must pay for this- with real money. I hope you are grasping the concept. Good luck.

thanx fellas, got it working

did the MX record/DNS thang and edited my sendmail.mc (then compiled to sendmail.cf) to reflect my domain name. don't know which one or if both did it, but it works
