Hotmail emails intermitantly fail when sent to our domain

问题提问于 2013年10月24日

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.hotmail.com please note the server in both headers

However after various attempts we found the successful emails were going through a different server reference the email header seen below.

Can i ask for an investigation to why emails are being rejected by one server and not the other. 

Many Thanks 

Andy
