Hi, Is your external DNS configured properly? You need to gave a PTR record created - your external DNS hoster should be able to help with this. If this is not the case you need to contact live hotmail and ask them why they are blocking mails from you. Leif

We contacted Hotmail and we did implement an SPF record for our domain. It has not happened since.
