Add and verify a domain

Publish DKIM and return-path, then send from that domain.

Add a sending domain, then publish the DKIM CNAME and the return-path CNAME. Sending stays blocked until both verify. The SPF include is optional.

Publish DNS

  1. Add the domain in the dashboard.
  2. Publish the DKIM CNAME {selector}._domainkey.{domain}{domain_id}.{dkim_zone}.
  3. Publish the return-path CNAME rp.{domain} → the return-path zone.
  4. Optionally add a TXT v=spf1 include:{spf_include} ~all.
  5. Click Check DNS.
Host Value
{selector}._domainkey.{domain} CNAME to {domain_id}.{dkim_zone}
rp.{domain} CNAME to the return-path zone
TXT on {domain} v=spf1 include:{spf_include} ~all. Optional.

We rewrite MAIL FROM to {id}@rp.{domain} so bounces come back to us.
