Attached is the updated patch. The most important difference compared
with the previous one is that this version allows to specify mailbox
URLs (pop://user:address@hidden) even when emacs movemail is used.
One notice: rmail-insert-inbox-text contains branches that move
inbox contents directly using (copy-file) or (rename-file). Currently
these are not used, since the controlling variable `movemail' is set
unconditionally to `t'. Are there any plans to use these branches? Or
can I just remove them?
ChangeLog entry:
2004-11-22 Sergey Poznyakoff <address@hidden>
* mail/rmail.el: Updated to work with movemail from GNU Mailutils
(rmail-pop-password,rmail-pop-password-required): Moved to
rmail-obsolete group.
(rmail-set-pop-password): Renamed to rmail-set-remote-password.
All callers updated.
(rmail-get-pop-password): Renamed to rmail-get-remote-password.
Take an argument specifying whether it is POP or IMAP mailbox we
are using. All callers updated.
(rmail-pop-password-error): Renamed to rmail-remote-password-error.
Added mailutils-specific error message.
(rmail-movemail-search-path)
(rmail-movemail-variant-in-use): New variables.
(rmail-remote-password,rmail-remote-password-required): New
customization variables.
(rmail-probe,rmail-autodetect,rmail-movemail-variant-p): New
functions
(rmail-parse-url): New function.
(rmail-get-new-mail,rmail-insert-inbox-text): Updated for use
with GNU mailutils movemail.
Accept mailbox URLs no matter what flavor of movemail is being used.

address@hidden version offers a much reacher set of

+
address@hidden version} of @code{movemail} is able to retrieve mail from usual

+
address@hidden version} is able to handle a wide set of mailbox
+formats, such as plain UNIX mailboxes, @code{maildir} and @code{MH}
+mailboxes, etc. It is able to retrieve remote mail using POP3 or IMAP4
+protocol. In the latter case, @code{mailutils movemail} can be
+instructed to retrieve mail using TLS encrypted channel.
+
address@hidden movemail} accepts mailbox argument in a @acronym{URL}
+form. The detailed description of mailbox @acronym{URL}s can be found
+in @ref{URL,,,mailutils,Mailbox URL Formats}. In short, an
address@hidden is:

address@hidden can be one of:

address@hidden @asis
address@hidden mbox
+Usual UNIX mailbox format. In this case neither @var{user} nor
address@hidden are used. @var{Host-or-file-name} denotes the file name of
+the mailbox file. E.g. @code{mbox://var/spool/mail/smith}.
+
address@hidden mh
+A local mailbox in @acronym{MH} format. @var{User} and
address@hidden are not used. @var{Host-or-file-name} denotes the name of
address@hidden folder. E.g. @code{mh://Mail/inbox}.
+
address@hidden maildir
+A local mailbox in @acronym{maildir} format. @var{User} and
address@hidden are not used. @var{Host-or-file-name} denotes the name of
address@hidden mailbox. E.g. @code{maildir://mail/inbox}.
+
address@hidden file
+Any local mailbox format. Its actual format is detected automatically
+by @code{movemail}.
+
address@hidden pop
+A remote mailbox to be accessed via POP3 protocol. @var{User}
+specifies the remote user name to use. @var{Pass} may be used to
+specify the user password. @var{Host-or-file-name} is the name or IP
+address of the remote mail server to connect to. E.g.:
address@hidden://smith:guessme@@remote.server.net}.
+
address@hidden imap
+A remote mailbox to be accessed via IMAP4 protocol. @var{User}
+specifies the remote user name to use. @var{Pass} may be used to

+address of the remote mail server to connect to.
+E.g.: @code{imap://smith:guessme@@remote.server.net}.

+Alternatively, the mailbox may be specified as a file name of the

+constructed by appending @code{rmail-movemail-search-path},

address@hidden POP inboxes
- Assuming you have compiled and installed @code{movemail}
-appropriately, you can specify a POP inbox by using a ``file name'' of
-the form @samp{po:@var{username}}, in the inbox list of an Rmail file.
address@hidden handles such a name by opening a connection to the POP
-server. The @env{MAILHOST} environment variable specifies the machine
-to look for the server on; alternatively, you can specify the POP server
-host name as part of the mailbox name using the syntax
address@hidden:@var{username}:@var{hostname}}.
address@hidden POP mailboxes
+ No matter which flavor of @code{movemail} you use, you can specify
+POP inbox by using POP @dfn{URL} (@pxref{Movemail}). A POP
address@hidden is a ``file name'' of the form
address@hidden://@var{username}@@@var{hostname}}, where
address@hidden is the host name or IP address of the remote mail
+server and @var{username} is the user name on that
+server. Additionally, you may specify the password in the mailbox
@acronym{URL}:
address@hidden://@var{username}:@var{password}@@@var{hostname}}. In this
+case @var{password} takes preference over the one set by
address@hidden This is especially useful if you have
+several remote mailboxes with different passwords.
+
+ For backward compatibility Rmail also supports two alternative ways
+of specifying remote POP mailboxes. Specifying inbox name in the form
address@hidden:@var{username}:@var{hostname}} is equivalent to
address@hidden://@var{username}@@@var{hostname}}. Alternatively, you may set
+a ``file name'' of @samp{po:@var{username}} in the inbox list of an
+Rmail file. @code{Movemail} will handle such a name by opening a
+connection to the POP server. The @env{MAILHOST} environment variable
+will in this case specify the machine to look for the server on.
+
address@hidden IMAP inboxes
+ Another method for accessing remote mailboxes is IMAP. This method is
+supported only by @code{mailutils movemail}. To specify an IMAP
+mailbox in the inbox list, use the following mailbox @acronym{URL}:
address@hidden://@var{username}[:@var{password}]@@@var{hostname}}. The
address@hidden part is optional, as descrbed above.
address@hidden rmail-remote-password
address@hidden rmail-remote-password-required
@vindex rmail-pop-password
@vindex rmail-pop-password-required
- Accessing mail via POP may require a password. If the variable
address@hidden is address@hidden, it specifies the password
-to use for POP. Alternatively, if @code{rmail-pop-password-required} is
address@hidden, then Rmail asks you for the password to use.
+ Accessing remote mail may require a password. Rmail uses the
+following algorithm to retrieve it:
+
address@hidden
address@hidden If the @var{password} is present in mailbox URL (see above), it
+is used.
address@hidden If the variable @code{rmail-remote-password} is
address@hidden, its value is used.
address@hidden Otherwise, if @code{rmail-remote-password-required} is
address@hidden, then Rmail will ask you for the password to use.
address@hidden Otherwise Rmail assumes no password is required.

+ For compatibility with previous versions, @code{rmail-pop-password}
+and @code{rmail-pop-password-required} may be used instead of
address@hidden and @code{rmail-remote-password-required}.
