Patent ID: 7320019

Claim:
A method of providing a system for automatically checking for an incorrect e-mail address in an outgoing e-mail communication, comprising: creating an incoming domain name list in a memory; receiving an incoming email communication; extracting a domain name from a sender's email address from the incoming email communication; storing the domain name in the incoming domain name list in the memory; checking if a domain name of an e-mail address associated with an intended recipient of an outgoing e-mail communication is included in the incoming domain name list in the memory; checking if a discrepancy exists between a domain name of an e-mail address associated with an intended recipient of an outgoing e-mail communication and a domain name included in the incoming domain name list in the memory by detecting when there is at least one but no more than a maximum number of discrepancies between a domain name in the domain name database and the extracted domain name; and transmitting the outgoing email communication if the domain name is included in the incoming domain name list, otherwise generating a prompt for a user to confirm an e-mail address associated with the intended recipient of the outgoing e-mail communication.
