Description

The SMTP service has two internal commands that allow the enumeration
of users: VRFY (confirming the names of valid users) and EXPN (which
reveals the actual address of users aliases and lists of e-mail
(mailing lists)). Through the implementation of these SMTP commands can
reveal a list of valid users.
