This article covers the SPF and DKIM authentication processes for DreamHost and how they are managed in Valimail. While only one of the two authentication methods is required for an email to pass DMARC, our recommendation is to configure both whenever possible.

The DreamHost mail server DKIM record will look like this, identifiable by _domainkey in the record and type TXT:

When you send emails through the mail server, they will be automatically signed. Most emails are sent through the mail server; webmail, mail client programs – anything that uses SMTP to send emails sends them through the mail server.

DreamHost supports 2048-bit DKIM keys.

NOTE: If you manage you domain in Valimail, you will need to add the DKIM key/s on your domain's configuration page in the Valimail platform.
