Abstract
Techniques are provided for email protection using email signatures based on signing tokens. One method comprises obtaining a signed email from an email sender. The signed email comprises a second hash value generated using a source version of the signed email embedded with a signing token of the email sender. A data record stores a first hash value, based on the source version, and the second hash value. The second hash value is obtained from the signed email and compared to: (i) a copy of the second hash value obtained from the data record and/or (ii) a comparison value generated using a regenerated version of the source version embedded with the signing token of the email sender. A delivery of the signed email to an email recipient may be based on a result of the comparison.
