Hotmail & Live@Edu blocking mail from Exchange Server 2003
I've set up an Exchange 2003 server at home. I have a registered domain, which points to my static IP provided to me by BT Business (my ISP).
Reverse DNS is set up and appears to be working, as I can send/receive mail from GMail without any issues (something I couldn't do when I tried this sometime back and had not got BT to set up reverse DNS).
I can send mail from an account at Live@Edu (we are using this for our pupil e-mail, but I've also got my own account set up for testing purposes). However, mail that I send from my Exchange server back to the account at Live@Edu does not get delivered - be it a newly created mail messae or a reply. I suspect using Hotmail would yield the same results.
Any ideas would be much appreciated on how to sort this one! Thanks in advance!
