We have one user who when external email is sent to him, you get a
bounceback stating:

"Delivery to the following recipients failed"

the data or the bounceback is as follows:

"Reporting-MTA: dns;email20.Enpointe.com
Received-From-MTA: dns;vms173003pub.verizon.net
Arrival-Date: Thu, 31 Jul 2008 14:02:51 -0700

Final-Recipient: xxx@xxx.com
Action: failed
Status: 5.7.1
X-Display-Name: xxx, xxx"

the user is able to receive Internal emails without issues. Any idea why
this could be happening only for 1 user out of thousands?

The system is a exchange 2003 system.

munging data can make it more difficult to diagnose an issue...that was the
full  text of the NDR?  the user has the correct smtp address?  you're
certain?  if you type in the address, and execute a ctrl + K, does it
resolve to his mailbox/display name?  whose is the reporting MTA?
vms173003pub.verizon.net?  is that you?  is the message even making it to
your server?

yes that was the full text of the ndr.  that is the correct smtp address,
I'm able to reproduce the ndr easily by sending an email to it from any
external company.

and yes, if I put that smtp address in my outlook internally, it does
resolve to the users name, and sending emails to the user does work,
Interally.

I have tried it with my verizon email account and my hotmail account.  Both
receive the same exact NDR.

I've event tried to telnet into my exchange server, here's the sequence of
commands I type (I'm using XXXs to block out my email info)
telnet xxx 25
ehlo live.com
mail from: xxx@live.com
rcpt to: xxx@xxx.com
data
test test this is a test
.

then I get a message saying the message is queued for delivery, and after
about a minute, I get the NDR in my .live.com email account.  I've looked at
the headers to the ndr and they are a.s follows:
Received: from [xx.xx.xx.xx] (helo=xxx.xxx.com)

the x's there are the correct ip address of my mail server, and the helo=is
the correct domain name of my mail server), so it does indeed look like
these NDR's are coming from my exchange server.

oh and I cant find anything in the logs or event viewer as to why its
rejecting either.

is it possible this mailbox is corrupt, if so how can you repair it without
having to create a new mailbox for the user?

i doubt that the mailbox is corrupt...I would turn up smtp protocol logging
on your Exchange server, to see if you can find out what's happening, that
way...all your mailboxes are on the same server?

no we have thousands of mailbox's spread out through out about 10 servers
over the world.  But all other mailbox's that sit on the same server and
there's about 100 all are working fine.
