One or more encrypted hash codes are computed from the email content and a private encryption key. The one or more hash codes are stored in an encryption memory, along with the data used to generate the one or more hash codes. The one or more hash codes are sent with the email content to the intended recipient. A verification request email is then received, containing a forwarded copy of the sent email. One or more verification hash codes are recomputed using the forwarded copy, and compared with the one or more hash codes stored in the encryption memory. A verification signal disclosing the verification result is sent to the intended recipient, via a non- email route.
