apop implementation

[Stephen Fischer]

It turns out we have several users that very strongly want to use APOP.  I
could find it mentioned nowhere in the documentation, so I'm presuming that
it's not implemented in the server code.  Has anyone made modifications to
implement APOP?  Are there suggestions on how to avoid sending cleartext
passwords that are acceptable to Eudora users?  We store the passwords in
cleartext currently so that we can use APOP on our current mail server.

Thanks,
Stephen
