The e-mail system was unable to deliver the message... but only on certain addresses.
Posted on 2007-03-29
A user is complaining that she cannot send email to a few people. I have noticed that the two email addresses we are having problems sending to are using Juno and Netzero. (not sure if that makes a difference)
We host our own Exchange 2003 server on our network, and can send and receive email to and from various accounts. (both internal and external)
There are only a few people having this issue, and we have tried sending email to this user from various internal addresses on the same Exchange server, and from a gmail account. Only the email sent from gmail was received by the address that is causing us trouble.
The complete error message is:
"The following recipient(s) could not be reached:
*****@juno.com on 3/28/2007 2:54 PM
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.
