Hmm.. pop in gnus?

Hmm.. pop in gnus?

[Ben Gertzfield]

-----BEGIN PGP SIGNED MESSAGE-----

*wave* Well, I've been lurking for a while, and I came up with this
question about everyone's favorite news 'n mail reader..

How does one go about using pop as a select method for a group?
Currently, I'm just using a shell-command to run popclient to fetch my
mail, but certainly there's a Better Way to Do It? *grin*

The docs are kind of unclear on this subject; they mention that other
select methods besides nnml and nntp exist, but don't describe how to
go about using them.

Thanks,

Ben

One doesn't.(*)  One uses POP as a spool file specification.  Here's
how:

(1) Compile movemail with POP support (Emacs configuration option
    --with-pop or something).

(2) Set the environment variable MAILHOST to where the POP server is.

(3) Use the following as nnmail-spool-file: "po:foo" where "foo" is
    your POP account.

I use this, and it works.  There's also pop3.el (comes with Gnus), but
I don't know how to use it.

(*) Sorry for nitpicking, just couldn't resist...

I'm also a happy user of movemail compiled with POP.

Movemail can perform various forms of automatic authentication (APOP
(similar to rsh/rlogin), KPOP (Kerberos)), depending on what
compile-time options are used.  If I didn't want this support, I'd
probably use pop3-movemail.

APOP is non-trivial though since the APOP code disappeared from the
FSF distribution about Emacs 19.29, and even if you resurrect the
required code, it needs to be installed setuid root.  But I made the
changes locally and I'm reasonably happy with it.

I think you're confusing APOP (which uses a challenge-response
authentication) with RPOP (which used the rsh/rlogin approach).

Oops.  You're quite right.

Sorry for any confusion and false hopes I might have given folks.

You can't do it in XEmacs, and the original poster uses XEmacs.
Someone should update XEmacs movemail.c.

pop3.el should work with XEmacs, but I don't know if anyone was brave
enough to actually try it.

thanks for the warnings. 
I tried it, before I read this, and I use it now, as it seems to work. :

Problems, I had:

The pop support is not at all well documented:

   I had to guess my setting:
      pop3-mailhost "auto.auto.tuwien.ac.at."
      nnmail-movemail-program 'nnmail-pop3-movemail
      nnmail-spool-file "po:albrecht"	; nil: don't ever read mail
;      nnmail-pop-password-required t

  Note that I have to leave nnmail-pop-password-required nil, or
  I'd otherwise be queried twice for the password since 
  pop3-password-required's value is t.

  Especially the pop3-mailhost setting was not easy to find.

  I tried 
      nnmail-movemail-program "movemail"
  but it tried to open the file /usr/spool/mail/po:albrecht :-)
  I guess that's a bug in the wrapper to the movemail program.
  (nnmail-spool-file is appended to rmail-spool-directory, before the
  check for "po:")

could someone add this (and the external-movemail description) to the
doc's ?

One does not, nor will one ever.  POP is geared towards one purpose:
transferring mail from a remote server to one's local machine.  It does
this quite well.  But it is a lousy way remotely store and access mail; it
was never intended to be used for this purpose.  POP simply is not IMAP.
Attempting to make POP work like IMAP is doomed to failure; the protocol
was never intended to be used in that fashion.

One could point the nnmail-movemail-program at the pop3-movemail function
and do the transfer with Lisp functions rather than an external program.
But no, pop3.el will never be transmogrified into nnpop (not by me, anyway
:).  Just dealing with the frequent (every 30 seconds of idle) server
timeouts is enough to discourage any sane programmer.

nnimap is, I hear, coming along.  It might even be ready by the end of the
Q-Gnus development cycle.

*pout* Hmph. All I wanted was a way to transfer mail from a remote
server to my local machine, but in Lisp :)

So I take it I should just keep my happy lambda shell-command in
there? :)

Oh, and I guess I should abandon all hope of Lisp-ifying my happy Perl
script that randomizes my signature.. let's see, was I supposed to
car or cdr there? Hmr..
