SMTP with service extensions (Extensible Simple Mail Transport 
Protocol).

Beginning with RFC 1869 and those later following, there were about 4 
RFCs that added various extensions to the SMTP protocol.

For our purposes on this list, we are just referring to one aspect -- 
that being where you are required to authenticate yourself by sending 
your account password to the ESMTP server.  Previously, SMTP did not 
require a password.  No matter if you had an account or not, your mail 
would relay through an smtp server.  This liberal use of the SMTP 
server is changing around the world as providers try to combat spammers 
from freely using their mail servers to relay their spam.  In some 
cases, we are now required to "Pop First" authenticate ourselves prior 
to sending mail, which verifies we have an account with the service.  A 
better, albeit more expensive method, is to authenticate with our 
password using one of the extensions of ESMTP.  Hence, we find some of 
our remote pop3 services opting for this type of authentication.
