Hotmail not delivering to my Microsoft Small Business Server 2003
Posted on 2007-11-23
My organization is using Microsoft Small Business Server 2003. The server has been up for over a year without any issues until today. The problem I am running into is email from hotmail accounts are not getting delivered. I think the problem is a hotmail issue, but I am not sure. Here is what I did to troubleshoot the issue:
1. Emailed my work account from my home SBS server. The email is delivered to my work account without any issues.
2. Emailed my work account from my Yahoo account. The email is delivered to my work account without any issues.
3. Emailed my work account from my gmail account. The email is delivered to my work account without any issues
4. Setup a new hotmail account and tried emailing my work account. The email is not delivered and I get a delivery failure notification in my hotmail inbox. The details of the delivery failue notification are as follows:
Arrival-Date: Fri, 23 Nov 2007 14:21:39 -0800
Diagnostic-Code: smtp;554 Transaction Failed (650058837:169:-2147467259)
I did a google search on the diagnostic code, and the two results I found stated there may be an MX record issue. I don't think thats the case because I can successfully email from my home SBS and my Yahoo account. My understanding is if there was a problem with my MX record, then nothing would be delivered to my work Exchange server because the other mail servers would be sending it to the wrong IP.
Any ideas on what this could be?
