DomainKeys Identified Mail

DomainKeys Identified Mail (DKIM) is an E-Mail authentication method. Dreamhost supports it by default in every domain’s DNS records. Enjoy

Seeing your DKIM DNS record

In the following, use your domain name in place of example.com.

1. Visit the Manage Domains page in Control Panel, and click the "[DNS]" link for the domain you wish to edit. You'll be taken to the domain management page.
2. Look in the left column, under "Record (example.com zone)", for lines marked "_domainkey".
3. See records, of type TXT, like the following:
   • o=~; r=postmaster@example.com
   • k=rsa; t=y; p=GIMfMA0GCSqGSIb3DQEBAQUAA4GNADCBiQKBgQCfVzZoj6YZph/1oTroL1NhkfHmMgZyuUyNBRVVPkXzQaeZMHMC+S+KxVP7TUPPQYZ6CKSELzqDwjv9jz10u3zx1eB+Bmqc8cYA2oxZdda3EaJ/LEYtIA1auXxHzY2qaElIToSLrV97il19F3m4p6V5M6Yho9zxfIfrlTHSECLsrQIDAQBA

History

Until October 2008, DreamHost didn’t support DKIM at all! However, in their October 2008 newsletter, they announced that they would be creating DKIM records in everyone’s DNS record. The newsletter said this DKIM implementation did not affect incoming mail.

Starting in February 2011 DreamHost started domainkey/dkim signing for all outgoing mail, Enjoy.
