we partner own a dedicated cpanel 6 server and having trouble with our own mail accounts for tekgear.net.au. these include sales@tekgear.net.au, info@tekgear.net.au etc.

when first setup all was fine but the day after any emails sent to these accounts were bounced and i was unable to send from these accounts. it will however allow login to horde etc.

nameservers are setup correctly and i have double checked all email logins and passwords.

our clients with .com .net etc domains have no trouble. any ideas would be appreciated.

Ok I just tested that email account and get A message that you sent could not be delivered to one or more of its
recipients. This is a permanent error. The following address(es) failed:

sales@tekgear.net.au
SMTP error from remote mailer after RCPT TO:<sales@tekgear.net.au>:
host tekgear.net.au [209.123.49.167]: 550-Host fred.unknowndns.net [162.42.210.233] is not permitted
550-to relay through server2.ebart.net.
550-Perhaps you have not logged into the pop/imap server in the last 30 minutes.
550-You may also have been rejected because your ip address
550-does not have a reverse DNS entry.
550 relaying to <sales@tekgear.net.au> prohibited by administrator

This is the error that you get when the domain is not listed in /etc/localdomains
How to fix
Login to SSH
pico /etc/localdomains
Add tekgear.net.au to the last line of the file,
Hit Ctrl+X [enter]
It then should work.

yeah i tried that earlier and it work. thnaks for the reply.

Did you restart the mail service

edited the file and restart mail service. all working well now. thank you.

No worries.
That error has always been related to the /etc/localdomains file.
I had email down for days aswell because of this error lost a lot of business over it.

yeah same here. luckily we had our old .net domain still running on another mail server. but yes potential clients lost from orders sent to .net.au.
