Office 365 and postfix – revisited

Since I wrote this post (a long, long time ago) – Office 365 now adds support for creating a trusted connector between your Linux/postfix environment and Office 365.

So as a reminder for me next time:

  • certificate
  • SASL for username/password
  • Postfix main.cf settings
  • Set up Office 365 connector and trusted IP end point
