Troubleshooting Email failure in Exchange 2007

Hi,

A message has been received by the Exchange 2007 store but failed to reach the User.  No NDR was received by sender or recipient.  The sender successfully sent a mail through earlier in the day but recorded a different IP address.  

Mail tracking reported following facts for the non delivered message:

Event ID #1 Receive    Source: SMTP
Event ID #2 FAIL          Source: Routing

Can you advise how I can take this further and understand where it failed?

Thanks

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

Check if it is stucked in queue.
Check message tracking.

Is this happening for one user only or all?

any logs in windows event logs (applications) regarding this failure ?
do you have any anti-spam running ?
buddlesAuthor Commented:
Those event IDs were from the tracker and no nothing in the queue.  Just this one mail from this sender.  

Nothing in the logs and yes to AV (Sophos) but nothing recorded there.  Recieved fine from them earlier in the day.


Can anyone help decipher the routing failure reason?

Apologies x-sam, completely missed your reply.  Thanks for the command, shows message was too large.  Why would MS not put this into the normal tracker GUI!

Excellent pointer.  Shows much more detail than the Tracker GUI.

Message was too large.

Well it would be there but you need to select appropriate options :-)
