Some sites use a method called POP for accessing users' inbox data
instead of storing the data in inbox files. By default, the
movemail can work with POP (unless the Emacs
was run with the option ‘--without-pop’).
Similarly, the Mailutils
movemail by default supports POP, unless
it was configured with the ‘--disable-pop’ option.
Both versions of
movemail only work with POP3, not with older
versions of POP.
No matter which flavor of
movemail you use, you can specify
a POP inbox by using a POP URL (see Movemail). A POP
URL is a “file name” of the form
hostname is the host name or IP address of the remote mail
server and username is the user name on that server.
Additionally, you may specify the password in the mailbox URL:
‘pop://username:password@hostname’. In this
case, password takes preference over the one set by
rmail-remote-password (see below). This is especially useful
if you have several remote mailboxes with different passwords.
For backward compatibility, Rmail also supports an alternative way of specifying remote POP mailboxes. Specifying an inbox name in the form ‘po:username:hostname’ is equivalent to ‘pop://username@hostname’. If you omit the :hostname part, the MAILHOST environment variable specifies the machine on which to look for the POP server.
Another method for accessing remote mailboxes is IMAP. This method is
supported only by the Mailutils
movemail. To specify an IMAP
mailbox in the inbox list, use the following mailbox URL:
password part is optional, as described above.
Accessing a remote mailbox may require a password. Rmail uses the following algorithm to retrieve it:
nil, Rmail assumes no password is required.
nil, its value is used.
If you need to pass additional command-line flags to
set the variable
rmail-movemail-flags a list of the flags you
wish to use. Do not use this variable to pass the ‘-p’ flag to
preserve your inbox contents; use
movemail program installed at your site may support
Kerberos authentication (the Emacs
movemail does so if Emacs was
configured with the option
--with-kerberos5). If it is supported, it is used by default
whenever you attempt to retrieve POP mail when
Some POP servers store messages in reverse order. If your server does
this, and you would rather read your mail in the order in which it was
received, you can tell
movemail to reverse the order of
downloaded messages by adding the ‘-r’ flag to
movemail supports TLS encryption. If you wish to
use it, add the ‘--tls’ flag to
