Hi there,

We are having problems with Hotmail users sending to our domain. when people send emails from our domain to Hotmail they send fine without any issues.

The Header below is from a failed email sent from a regularly used Hotmail account and which mostly fails however out of 10 emails 1 or 2 will get to there intended destination. People who are affected are using both mail-clients outlook, thunderbird and browsers like internet explorer and firefox to send emails.

Failed email was bounced by postmaster​@mail.hotma​il.com
please note the server in both headers

Many Thanks
