Couple of my users are getting "Message Delayed" messages back for some domains that they send mail to. i.e. returned after a certain number of retries. Below is an example of the details. Has anyone come across this and know whats happening as I cannot find anything on it.
Example: Reporting-MTA: dns; smtp.ourdomain.com Received-From-MTA: dns; Mymachine (unverified [IPADDRESS]) Arrival-Date: Thu, 13 Jun 2002 11:00:37 +0100 Final-Recipient: rfc822; [EMAIL PROTECTED] Action: delayed Status: 4.0.0 (Persistent transient failure - no additional status information available) Remote-MTA: dns; mail.domainX.com Diagnostic-Code: smtp; 454 5.7.3 Client was not authenticated.
