Mail server webmail not working
I have a problem with the Lion Webmail (or mail server in general). First I can log to webmail just fine, but when sending a message the message goes to sent items, but it is not delivered (but no returning error mail). I suspect I have some sort of DNS or relaying issue, but have gone through everything over and over and found nothing that looks strange. Has anyone else seen this issue?
Also when I try to send e-mail from an external account (gmail) to the lion server hosted e-mail adress I get an error message stating the following:
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).
Any brilliant minds out there able to help?
