Over the past few days, I have had users telling me that people whom are trying to email them are getting a bounce message. When I ask them what it is, they tell me it is this:
The following recipient(s) cannot be reached:
firstname.lastname@example.org on 4/6/2009 9:23 AM
The e-mail system was unable to deliver the message, but did not report a specific reason. Check the address and try again. If it still fails, contact your system administrator.
< jripqe1.jr.local #5.0.0 smtp; 5.1.0 - Unknown address error 554-'5.7.1 This message has been blocked because the return email domain is invalid.(failed to obtain DNS record for domain jr.com)' (delivery attempts: 0)>
We can send email just fine....any ideas????
