  6. Click Save.
  7. Then click Configure External Dependencies.
  8. Click Outbound Settings.

  11. Go to Apps > G Suite > Gmail > Settings For Gmail.
  12. Click on Advanced Settings.
  13. Scroll down to the Routing section.
  14. In Outbound Gateway, paste the outbound relay host address you copied earlier.

Note Changes may take several minutes to propagate.
  • If you authenticate outgoing email using an SPF record or DKIM, you may need to update your configuration.
  • Replace with or add the SPF record: v=spf1 include:_spf.prod.hydra.sophos.com ~all

If you are certain that you do not have any third parties sending mail on your behalf, and all your outbound mail is routed through Sophos Email, you can add a hard fail instead: v=spf1 include:_spf.prod.hydra.sophos.com -all.

Note This means that your mail needs to be sent from Sophos Email to be accepted by the receiver's mail servers (if they carry out SPF checks).
