Rebooting our server sent an email 10 days late
Posted on 2009-02-23
At the weekend I had to reboot our Exchange (2003) server and I received a reply from an external recipient saying that he had just received an email that was originally sent out on the 11th, over 10 days ago.
The email was sent by the Director to two external and one internal recipients. All but one recipient received the message.
Looking at my logs I see that the original message was sent on the 11th as I got a 1031 (The outgoing message was successfully transferred) message for all 3 recipients. The log entry in question is:
2009-2-11 14:23:4 GMT - - server33.donhost.co.uk EXCHANGE-HO - firstname.lastname@example.org 1031 DC4B7B0CDEE9A741AE768D38BAA8109A019DF4@exchange-ho.internaldomain.local 0 0 8937 2 2009-2-11 14:23:3 GMT 0 - - - email@example.com -
When I rebooted the Exchange server and it resent the email. It only sent it to the above recipient and I got the following in my log:
2009-2-21 10:0:30 GMT - - server32.donhost.co.uk EXCHANGE-HO - firstname.lastname@example.org 1031 DC4B7B0CDEE9A741AE768D38BAA8109A019DF4@exchange-ho.internaldomain.local 0 0 8937 2 2009-2-11 14:23:3 GMT 0 - - - email@example.com -
Again a 1031, but this time he received the email.
Can anyone shed some light on what is going on here please. I thought a 1031 meant the message had been sent, or at least received by the recipients server and that our Exchange server would then not try to resend it or store it in a queue awaiting a reboot?
