is in fact easier to insist that the customer check for mail first, thus
initiating the POP authentication. In fact this is trivial when the
client uses something like Netscape as a mail client. If the connection
drops before the outgoing queue is clear then the user need only initiate
the connection by attempting to check for e-mail and everything seems to
happen in the right order.
Of course if your authentication daemon doubles as a dial-up manager,
then it's almost as easy to convince users to always use it. Writing a
dial-up manager is not difficult, but it's an entirely different kettle
of fish too.
