Class User embeds the profile information; it provides two methods to
open and close a connection to the mail server: openPopServer() and
closePopServer() . In addition it provides getter and setter methods to access
the profile parameters.
Several methods have package visibility. The constructors can load the
information from a row of the database represented by a ResultSet object, or
create a brand new profile with only the name.
