Hi Folks,
Basically I have my domain howcode.com bought at DomainMonster.com. I have set it all up to point to MediaTemple nameservers and everything works - mostly - fine. I have registered an email address 
[email protected].
The setup is, I presume, working correctly. I can successfully send emails with the account. And I presume I can receive them - but the problem is, nobody can send them to me.
Emailing from a regular, non-Googlemail account appears to work fine but it never arrives in the inbox.
But when you email from a GoogleMail address, an error message is instantly returned saying this:
  Delivery to the following recipient
  failed permanently:
[email protected]
  
  Technical details of permanent
  failure:  
Google tried to deliver your
  message, but it was rejected by the
  recipient domain. We recommend
  contacting the other email provider
  for further information about the
  cause of this error. The error that
  the other server returned was: 550 550
  relay not permitted (state 14).

  Hi
I thought this may be something to do with my MX DNS settings. They are setup like so:
MX name: howcode.com
TTL: 43200
Type: MX
Data: 10 mail.howcode.com.
The A-Record for mail.howcode.com is setup like this:
Name: mail.howcode.com
TTL: 43200
Type: A
Data: 205.186.187.129
Is this what's going wrong with the issue?
Thanks very much
Jack
