Hi all,

I am trying to sort out a problem which is causing quite some hassle in the company.

Any emails sent from Hotmail to our domain are not being received; the sending user receives an email from the Hotmail postmaster stating "Delivery Status Notification (Failure) - Delivery to the following recipients failed."

We are not blocking any emails and all other domains can send emails to our domain just fine.

Can you please guide me as what this could be?

Thanks
