HI, can you explain this??
If you are using PowerMTA 4.5r6 or later then you can also use mx-rollup-list feature to consolidate Microsoft related domains into one queue. This will improve resource utilization. For example, Microsoft EU and APAC :
# Microsoft
mx eur.olc.protection.outlook.com outlook-eur.rollup
mx apc.olc.protection.outlook.com outlook-apc.rollup
whereis hotmail.com
Thanks!!
hotmail.com does not resolve to above MX so it will not be included in above rollup queues.
