Difference Between DomainKey And DKIM
DomainKeys Identified Mail (DKIM) is the successor of Yahoo DomainKeys. Both DomainKey and DKIM have similarities, however, DKIM has an additional aspect of Cisco’s Identified Internet Mail standard (IIM). The enhancement of this standard gives more flexibility and security than DomainKeys alone. Below is the list of main differences between DKIM and DomainKeys:
- DKIM allows multiple signature algorithms whereas DK only allows one.
- DKIM has more options that allow you to validate the header as well as the body.
- DKIM allows third parties to sign.
- DKIM allows self-sign the DKIM-Signature header field; it helps protect against modifications.
- DKIM gives you an option to use the wildcard on some of the parameters.
- DKIM supports signature timeouts in the DNS.
