Hotmail can reply to email but not send new email


I am experiencing a very strange issue with my box…

Trying to send a email to an account of my box from a or and it never gets delivered. No bounce back or anything.

But for some strange reason, if i reply to a email sent from a or it goes through and they receive.

Any ideas what this could be?


Check your server’s IP and hostname in to see if you’re on any blacklists.
