I have my dedicated server set up to use an external email provider for our email. However, at random, messages are being blocked by my server and returned to the sender with the following message:

Reason: Remote SMTP server has rejected address
Diagnostic code: smtp;550-asmtpout024.mac.com [17.148.16.99] is currently not permitted to relay through this server. Perhaps you have not logged into the pop/imap server in the last 30 minutes or do not have SMTP Authentication turne
Remote system: dns;macnightowl.com (TCP|17.148.16.99|53653|208.79.206.29|25) (server.makingtheimpossible.net ESMTP Exim 4.69 #1 Fri, 21 Nov 2008 15:59:17 -0700 )
So the question is: In simple English, how would I fix Exim in order to allow for the mail to go to the third-party server? I've entered the MX and MX IP info in the Exim whitelists, but that doesn't seem to help.

So -- help?

Peace,
Gene

Not really enough information here... so many server names and IPs, and we haven't a clue who is sending mail to what, and what is the remote server and what is the local server.

:confused:

That looks as if the recipient domain isnt set up in your localdomains config, as thats the message shown to un-authenticated mail clients that try to send mail to non-local domains.
