NDR message

[adfreek]

Running Exchange 2003 on Windows 2003. Looking for some help on what this means? I'm guessing it might be due to the fact that I don't have a reverse DNS zone and this particular recipients smtp server could be performing reverse lookups for validation? I can send outbound mail to other servers successfully?

Thanks

Hi, I'm getting the exact same NDRs back for some of my users on what I thought was one (now two) email addresses. I've checked blacklist sites...to make sure we're not on any, checked many other help sites and the most I've come up with is it may be a remote site problem. Anyone else have any ideas to check this?

Normally you only get this message for 2 reasons:

1. You are blacklisted

2. You are attempting to relay mail.

See the following MS article:
