G'day All,

There is a small bug in GNU Emacs POP3 handler. This is an
Emacs/Cygwin bug, not, say, an Emacs/Linux bug. When GNU Emacs
movemail.exe transfers mail from MAILHOST, it creates a temporary file
that is made by concatenation of ".newmail-" and whatever the POP name
from rmail-primary-inbox-list is set to. That name begins with
"po:<username>", so the generated file name into which movemail is
going to move mail is

   .newmail-po:<username>

Now, Cygwin, like Windows NT, has problems with colons in file names,
so, movemail fails, if the generated file name is supposed to be, e.g.,

   .newmail-po:xyzzy44:ouch.ucs.indiana.edu

A file such as .newmail-po:xyzzy44 can be generated (if "ouch" was to
be declared throuth the MAILHOST variable), but it would show up as
.newmail-po in the directory listing. Still bad.

A simple remedy is to use the

   (if (eq system-type 'windows-nt)

clause in rmail.el and replace it with

   (if (or (eq system-type 'window-nt) (eq system-type 'cygwin))

Happy hacking,

==
