Set up outbound email handling with Exchange and other clients
This document guides you through the process of directing all outbound email via Sophos Email. For Exchange, this requires an SMTP Connector to be configured on your Exchange Server.
To set up outbound email handling:
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.
Confirm that outbound mail is flowing by sending a outbound mail to an external address.
- Sign in to Sophos Central.
- Go to .
- Change the direction to outbound.
- Refresh the screen until you can see the details of the test email you have sent.
