Meanwhile, no Microsoft mail server tries to connect to my mail server, so I'm seeing a DSN failure when delivery isn't even attempted.
What can I do to help resolve this?
There is some sort of problem when Outlook.com (or live.com as this account is) email users send to my mail server. I just sent myself a test and, within 5 seconds, Outlook.com popped up with a DSN failure message. I am able to send to gmail successfully.
Clients and partners who use outlook.com, though, are having trouble sending me email.
