  A side point to the discussion: POP is intended for a simple post office
pickup/delivery service, and it is by no means inconsistent with its design
to add the XTND XMIT verb and use it for a bidirectional channel. Some of
the other extensions (news service) seem harder to justify, but are
simple-minded enough that no-one actually gets angry when they're mentioned.

  IMAP, on the other hand, is by design a unidirectional service, with a
fair bit of complexity to allow a wide range of services.  The
author/specifier has good reason for not wanting to add a
comparable-complexity posting service!  And I respect his wishes, even
though I'd personally prefer that he invent that particular hairy beast
(:-)).

  This works fine at York: I suspect something is weird...  to misquote

I suspect some sort of weird characters: we ran Eudora and pop here for
some years and the messages were accepted by our zmailer-using hosts.
The machine running the pop service was running sendfail(8), though, and
may have rewritten them into sanskrit for all I know (:-))
