Mail disappearing into the ether

My website is now up and running, I'm now having problems with mail.

I can check mail, and send email, however I'm neither receiving or sending anything?

I setup the DNS entries on my domain service to:

A record: @ xx.xx.xx.xxx
A record: mail xx.xx.xx.xxx
A record: www xx.xx.xx.xxx

MX record: mail.mysite.net. priority 10

I'm guessing it's this thats causing the problem, help appreciated.

 

Can you post the real domain name here?

 

The domain is icanlearnit.net

This is what was in /var/log/mail.log:

Code:

Looks like your mailserver is down at the moment (or it cannot be reached)
Are you behind a router / firewall, and if so, did you forward / open the correct ports?

 

That seems to have been the issue, I forgot to open the port, DOH!

Thanks for pointing it out.

Still can't send emails, but can receive them now. Will have to investigate further why I cant send them.

 

Im still having a problem with outgoing mail:

Code:

Dec 10 07:46:06 elmo postfix/smtp[20068]: 7DACCA5C342: to=<[email protected]>, relay=none, delay=56510, delays=56490/0.06/20/0, dsn=4.4.3, status=deferred (Host or domain name not found. Name service error for name=googlemail.com type=MX: Host not found, try again)
Dec 10 07:46:06 elmo postfix/smtp[20067]: 5AA7CA5C340: to=<[email protected]>, relay=none, delay=56569, delays=56549/0.04/20/0, dsn=4.4.3, status=deferred (Host or domain name not found. Name service error for name=gmail.com type=MX: Host not found, try again)

/etc/resolv.conf

Code:

nameserver 192.168.1.1

Which is the router.

 

Please put this in /etc/resolv.conf instead:

Code:

nameserver 145.253.2.75
nameserver 193.174.32.18
nameserver 194.25.0.60

These are three DNS servers that I know work.

 

I tried updating the resolv.conf and the mail log now shows:

Code:

Dec 11 00:00:07 elmo postfix/smtp[11848]: connect to gmail-smtp-in.l.google.com[66.249.93.114]: Connection timed out (port 25)

Could it be my router stopping the server from connecting?

 

Yippee,

Got it working it was my router! again.

thanks for your help.
