Hello, Running Exchange 2007 on an SBS and we are unable to receive from hotmail. All other domains can send fine (gmail, etc.) Performed the telnet test, and surprisingly enough, I am able to send through telnet. But when I send from my hotmail account, I don't get anything and I don't even see anything in the queue. Any ideas?

You don't get an NDR in the Hotmail mailbox, even after a couple of days?Ed Crowley MVP "There are seldom good technological solutions to behavioral problems."

So I actually do get an NDR, almost immediately. I did not notice it before because incoming mail to this hotmail account was being forwarded to another account. I get the following: --------------- This is an automatically generated Delivery Status Notification.Delivery to the following recipients failed.admin@alumadeck.com----------

Do you have any antispam and/or antivirus appliance or service between the Internet and your Exchange server or on your Exchange Server?Ed Crowley MVP "There are seldom good technological solutions to behavioral problems."

No - and no changes have been made recently...

If that's all you're getting, it's going to be hard to figure out what might be wrong. If you haven't done so already, enable SMTP protocol logging and see if you can see the connection attempt in the logs. Ed Crowley MVP "There are seldom good technological solutions to behavioral problems."

I agree, I was getting too frustrated with this. However, this morning, magically, it started working again! Emails from Hotmail are coming through fine...
