SpamHero is a great solution for customers using Microsoft Office 365 that want better spam filtering.

Basic configuration

There are only two steps required for setting up SpamHero with Office 365:

  2. Switch the MX records for your domain to the ones assigned to you by SpamHero (and remove all other MX records). The MX records can be found on the Settings > Mail delivery host page under the Required MX settings section of the page.

Important: To avoid interruptions in mail delivery, SpamHero should be added as a "Connector" in the Office 365 control panel.
