I can't get TFS 2010 to send email alerts. I've tried setting up everything mentioned here:
It's configured to send to a local IIS SMTP instance. SharePoint 2010 is on the same box and is also configured to use the same local SMTP server and it works fine sending emails, no problem. It's also using the same "from" email address as TFS is configured to without issue.
TFS isn't even trying to send anything as far as I can tell - I don't see anything from it in the SMTP log (C:\Windows\System32\LogFiles\SMTPSVC1...).
I have the default "My Work Items changed" alert set up and enabled. I try logging in as another user, assigning a work item to me, then assigning it back...nothing happens...no email. I don't see any error in the event viewer from TFS.
What can I do to troubleshoot this?
