DKIM signing is on by default in ReachMail. All messages with sign with DKIM Keys automatically. Customers can request DKIM signing for their own domain at no extra charge.
To do so:
- Setup a DKIM signature
- Add CNAME record to k1._domainkey.<domain.tld> with a value: dkim.rmdlvry.com
- e.g. k1._domainkey.mydomain.com has CNAME record with value: dkim.rmdlvry.com
- Contact Support@reachmail.com to let us know which domain you have used.
Customers that implement DKIM signatures on their DNS must contact email@example.com for custom key signing to be enabled on their account.
It is also recommended that customers implement an SPF record along with DKIM signing for best results.
