3.04
Use another tmpdir instead of "out" in t/testcommon.pl's server config
so an "out" directory is not left in the source directory after tests.
make t/jobserve.t - jobserve.pm requires HTML::Form

3.03 2013/12/31
Moved tests to t/*.t. Changes for Win32: if Win32, don't install SIGUSR1
handler, don't try to use IO::Select->can_read, don't call getgrnam

3.02 2013/12/28
Updated tests to reduce duplication and hardcoding.

3.01 2013/12/27
To make it pass tests (and actually build), stopped using ".inst_dir"
in distrib directory to build the scripts, since it was not being created
and therefore was causing immediate failure. Instead used hardcoded value.

3.0 (from 2.* by Mark Tiramani) 2002/08/09
Turned Mail::POP3Server into Mail::POP3 - redesigned it to be as follows:

Mail::POP3::Daemon does the socket-accepting.
Mail::POP3::Server does (most of) the network POP3 stuff.
Mail::POP3::Security::{User,Connection} do the checks on users and connections.
Mail::POP3::Folder::* classes handles the mail folders.
Mail::POP3::Folder::virtual::jobserve presents a jobserve search
  (using the username as params) as a POP3 mailbox.

This involved turning the previous Mail::POP3Server "inside out", since
it more or less only had as an interface a "startserver" method.
