I've installed ISPConfig 3 on my VPS using the brilliant tutorial here: http://www.howtoforge.com/forums/showthread.php?t=56541
However, if I go to send an email to an account I've set up on the server I get the following error:
Delivery to the following recipient failed permanently: firstname.lastname@example.org
Technical details of permanent failure: DNS Error: DNS server returned answer with no data
I've checked my DNS records for that domain, and they are as follows:
setanta A 80.xx.xx.xx mail.gravex.co.uk MX 10 80.xx.xx.xx NS ns1.6sync.net. NS ns2.6sync.net. NS ns3.6sync.net. ftp A 80.xx.xx.xx mail A 80.xx.xx.xx dail A 80.xx.xx.xx www A 80.xx.xx.xx . A 80.xx.xx.xx
I've also tried to send an email from squirrelmail. I've had no errors come back but I've not had the e-mail come through either.
I'm not sure what's going on, as I thought adding mail.gravex.co.uk as an MX record would work, but I don't think it has. What do I need to do to make it work?
I've changed the MX record so
gravex.co.uk points to
mail.gravex.co.uk. However, e-mails still can't be delivered to the account due to the same error.
Also, the DNS server is handled by 6sync, not ISPConfig 3.
