Abstract
An email, which includes a header and historical information, is created. The header comprises a destination email address, which comprises a name of an addressed recipient of the email and a domain name of the destination email address. The historical information in the email comprises an approved address for a previously exchanged email with the addressed recipient. The first approved address is compared to a corresponding portion of the first destination email address.

The warning comprises both the approved address, and an unapproved address list that comprises the first destination email address.
