I didn't know that -- clearly, I didn't look deep enough. I saw it had APOP
support, which is the standard, but didn't notice the S/Key.

For reasons which now escape me, I hacked straight 2.4, not the beta, so maybe
a change was made in between.

Unfortunately, I may *still* need to hack the bloody thing. The client is
Netscape Communicator, which definitely doesn't understand APOP or (it
appears) S/key, and so the "bad password" message in pop_pass.c needs to
include the s/key challenge for the user (since Netscape only reports error
messages, not OK responses.) Maybe that was fixed in the beta as well.
I'll look at the port in detail before going further.
