DomainKeys Identified Mail (DKIM) adds a digital signature to emails. This signature lets the receiver verify that an email was signed by the owner of the domain and hasn't been altered in transit.
The security of DKIM depends on the key size. Larger keys are harder to crack but require more processing power.
