Consistency between recipient and signer email address

Hi everyone,

is it possibile to check the consistency between the recipient and signer email address. In other words: the email address the agreement is sent to, should be the same that the external recipients uses to sign the document with.

For instance, I'd like to make sure that an agreement sent to example@email.com is also signed using the very same example@email.com. To sign, the external recipients use an account created beforehand with a Certification Authority.

Any advice?
