- Several others have commented on how to work around these limitations
- somewhat. However, the fundamental problem here is that you're trying to
- use POP3 as a solution to a problem it was never intended to solve.
-
- POP3 is intended as a kind of reverse SMTP; it lets machines download mail
- from a central server machine. By and large these systems are incapable of
- operating an SMTP server; this is the primary reason for having POP3. Now,
- a protocol that's designed to download messages in this way doesn't have
- to worry about a lot of things:
-
- (1) Folders are irrelevant since the POP server is just an incoming maildrop.
- (2) Keeping copies on the server is unnecessary (same reason).
- (3) Partial message downloads are not provided for since server operations are
- an all-or-nothing sort of deal.
-
- The sort of usage you're describing is that of a lightweight mail client with
- little or no client message store. The PathWorks and MailWorks clients all
- operate this way, as you noted. The Internet equivalent isn't POPx, it is
- IMAP. IMAP was explicitly designed with this sort of thing in mind. It
- supports access to multiple folders, messages are only kept on the server,
- partial message operations are provided, folder operations are provided, and
- so on and so forth. IMAP is much more complex than POPx because of all the
- added functionality it provides.
-
- Various IMAP clients are available. The one I know of for the Mac is called
- Mailstrom (from Stanford).
-
- IMAP servers for VMS are harder to come by. As far as I know we'll be releasing
- the first one as part of PMDF V4.2, which is currently in field test.
