Mail-From - Authenticates the transaction by sending an email to the contacts email account. The email must be returned from the same email account as the one it was sent to.
Since you're asking this question you probably should go with Mail-From...just leave the line blank and return the email.
To explain in a nutshell:
Crypt-PW - Authenticates the transaction by password. Easiest method for webmasters.
PGP - Authenticates by PGP key. Probably the safestway to do this.
