Supports the industry standard 
method of verifying users by 
embedding an identifier within 
the message. The server can use 
a combination of the identifier 
and the IP address of the SMTP 
server used to transmit the 
message. This feature reduces 
the risk of domain spoofing and 
other message problems.
