Hello folk!

I have SBS 2003 Premium with Exchange mail server SP2. Two of my mail users can't recieve messages from certain person from certain organization. Others can.

Here is NDR report:

-----------------------------------------------
This is an automatically generated Delivery Status Notification.

Delivery to the following recipients failed.

recipient@mydomain.com

Reporting-MTA: dns;myserver.mydomain.com
Received-From-MTA: dns;smtp.domain.com
Arrival-Date: Tue, 12 Jun 2007 08:48:08 +0200

Original-Recipient: rfc822;recipient@mydomain.com
Final-Recipient: rfc822;recipient@mydomain.com
Action: failed
Status: 5.2.1
X-Display-Name: User =?unicode-1-1-utf-7?Q?+ARA-uki+AQc-?=

-----------------------------------------------

About this error I found these answers:
http://support.microsoft.com/kb/284204

it says: message too big or SID not found.

I checked the size and it's only 2Kb. Users are members of my AD and have SID, he gets all his emails from other people inside and outside organization.

Any other suggestions?

Thanx, A

Hi,

I am having a similar problem with one user unable to send to one external recipient. As far as we know the recipient gets mail from anyone else internally and externally and the sender can send to anyone else internally or externally.

The sender gets an NDR #5.2.1

We've checked user, mailbox, and mailstore permissions. Everything appears fine.

Did you have any luck in getting your issue sorted?

Any help would be greatly appreciated.

Cheers

Rob
