View Full Version : [SOLVED] postfix and FQDN

September 4th, 2012, 09:13 PM
I am trying to setup postfix. I have followed several guides, they say the same thing and I am mailing everytime

I think my issue is the domain name.
I don't really have a domain so I used no-ip.

myhostname = philo.something.no-ip.org

philo is my system name/ my as in "server@philo:~$"
something.no-ip-org is linked to my public ip address.

Am i misunderstanding the concept of a FQDN?
Technically something.no-ip.org is my router not that box.
Isn't that why i used "philo"?

Edit: I do seem to get the email in the mail folder of the user who sent, but im trying to send it to an external address.

A FQDN needs to be something you have a DNS record for. If you are using no-ip's free service, you do not have a record for anything.yourdomain.no-ip.org, and so the FQDN you configure in your server must be just yourdomain.no-ip.org. The internal hostname you have configured on your computer is irrelevant.

ok that makes sense. SO I set

myhostname = something.no-ip.org
mydomain = something.no-ip.org

I restarted postfix

mail me@gmail.com < test.txt

still nothing

Thread moved to Server Platforms.

edit: is anything showing up in Postfix's log? It's commonly found at /var/log/mail.log

I restarted postfix

mail me@gmail.com < test.txt

still nothing



to check that it is not stuck in the queue. If the queue is empty

sudo tail /var/log/mail.log

Well, it seems to work fine... Have you checked your spam folder (especially if you have a dynamic IP)? Also, can you recieve mail on your server? If something went wrong on gmail's side, you should have received a notification on root@something.no-ip.org.
