Set up a sending domain (SPF, DKIM, DMARC)

Mail signed from your own verified domain reaches the inbox. Mail from a shared pool often does not. This is why Mule Mail will not let you send from an unverified domain.

What you add

When you add mail.yourcompany.com, Mule Mail generates:

• SPF: a TXT record authorising the sending service.
• DKIM: one to three CNAME records that cryptographically sign your mail.
• DMARC: a policy record telling inbox providers what to do with mail that fails.
• Tracking CNAME: so open and click links are on your domain.
• Return-path CNAME: so bounces come back to the right place.

Verifying

Add every record exactly as shown, then click Verify. DNS can take up to a few hours to propagate, though most hosts are minutes. Mule Mail re-checks every 24 hours and emails an admin if a record breaks.
