Pine in its current implemention as you described it does not work with
any INN installation that requires both AUTHINFO and MODE READER.

No server which requires AUTHINFO before MODE READER actually requires
MODE READER at all; you don't need to send MODE READER to such a server.
(I can make this statement because I believe, with a fairly high degree of
certainty, that only INN actually requires MODE READER, and INN does not
require AUTHINFO before it.  I also know that Diablo, the only server
known to require AUTHINFO before MODE READER, doesn't require MODE READER
at all.)

I do know how INN works, though.  :)
