External email oddity (Exchange 2007)

CLAWS · 26 Oct 2011 at 10:22

Hi there, a very odd issue I have come across :confused:

Last week I setup a new login account for a new starter. The following day after the account was created I then renamed the account as per advice from HR. I did the rename in Active Directory and on Exchange Server 2007. All this went fine and when the user joined us they logged in fine and without any issues.

The oddity is that she can email internally and externally without any problems. She can also receive internal emails without issue but she is unable to receive external emails.

I have killed her login and exchange accounts both and recreated them from scratch and then logged her in and setup her outlook profile. I then email her from my hotmail account and I receive a Delivery Status Notification (Failure)

I have checked settings on the exchange server and nothing has been disabled or hidden. Any ideas because I am fresh out :confused:

What does the NDR say?

Damn, sorry completely missed that part -

Delivery to the following recipients failed.

[email protected]

Also I have just gone through message tracking on exchange server to see if the email I sent from hotmail has even hit our server but all search queries come up blank.

I've had this when the mail address was set-up for the domain prefix rather than the external email. I.e the person was set up as [email protected] instead of [email protected]

Delivery to the following recipient failed permanently:

[email protected]
Technical details of permanent failure:
DNS Error: DNS server returned answer with no data

was the error message

Not the same unfortunately

Ok, working on it. Cheers by the way

Hope this is correct -

This is an automatically generated Delivery Status Notification.

Delivery to the following recipients failed.

That's the useful bit. Looks like there is some policy or rule which is restricting delivery.

Found it!!

We use mailmarshal as our email filter. Went through some of the rules and reloaded the user group to include the user.

Something so simple easily overlooked due to tunnel vision.

Cheers for that Burnsy! I'm sure you've rescued you me before as well. I'd happily buy you a pint or few mate
