For example, the following invocation: + +@smallexample +movemail /var/mail/smith INBOX +@end smallexample + +@noindent +moves messages from file @file{/var/mail/smith} to file @file{INBOX}. + +You will probably never have to run this program manually. It is +intended as a replacement for @command{movemail} from GNU Emacs. The +@command{movemail} program is run by Emacs @code{Rmail} +module. @xref{Rmail,,,emacs,Reading Mail with Rmail}, for detailed +description of @code{Rmail} interface. + +Mailutils version of @command{movemail} is completely +backward-compatible with its Emacs predecessor, so it should run +flawlessly with older versions of Emacs. Emacs version 21.4, which is +being developed at the time of this writing, will contain improved +@code{Rmail} interface for work with mailutils @command{movemail}. + +@menu +* Movemail Options:: Description of the Available Options +* Summary:: Short Movemail Invocation Summary +@end menu + +@node Movemail Options +@subsection Movemail Options + +This subsection discusses @command{movemail} options from the point of +view of an Emacs @code{Rmail} user. + +To set various options to @command{movemail} from @code{Rmail}, use +@code{rmail-movemail-flags} variable, or @samp{Rmail Movemail Flags} +section from the menu. + +Some POP servers return messages in reversed order. To fix the +order, use @option{-p} option or its synonym @option{--reverse}. + +If the remote server supports @acronym{TLS} encryption, use +@option{--tls} to instruct @command{movemail} to initiate encrypted +connection. + +Quite a few options control how @command{movemail} handles mail +locking (a way of preventing simultaneous access to the source +mailbox). By default, before accessing mailbox @var{file}, +@command{movemail} will first see if the file named +@file{@var{file}.lock} (so called @dfn{lock file}) exists. If so, it +will assume that the mailbox is being used by another program and will +sleep one second. If @file{@var{file}.lock} file disappears after this +wait period, the program will proceed. Otherwise, it will repeat this +action ten times. If after ten wait periods the lock file does not +disappear, @command{movemail} gives up and exits. + +If the lock file does not exist, @command{movemail} will create it, +thereby indicating to other programs that the mailbox is being used, +and will proceed to copying messages to the destination file. When +finished, @command{movemail} closes the mailbox and removes the lock +file. + +Several options control this behavior. To change the default sleep period +use @option{--lock-retry-timeout}. Its argument is the timeout value +in seconds. + +To change number of retries, use @option{--lock-retry-count}. For +example, setting @code{rmail-movemail-flags} to + +@smallexample +--lock-retry-timeout=2 --lock-retry-count=5 +@end smallexample + +@noindent +instructs @command{movemail} to make five attempts to acquire the lock +file, with two-second intervals between the attempts. + +You may also force @command{movemail} to remove the lock file if it is +older than a given amount of time (a so called @dfn{stale lock +file}). To do so, use the following option: + +@smallexample +--lock-expire-timeout=@var{seconds} +@end smallexample + +The @option{--lock-expire-timeout} sets the number of seconds after +which a lock file is considered stale. + +There are special programs that can be used to lock and unlock +mailboxes. A common example of such programs is @command{dotlock}. If +you wish to use such @dfn{external locking program} instead of the +default mailutils locking mechanism, use option +@option{--external-locker}. Argument to this option specifies the full +name of the external program to use. + +@node Summary +@subsection Summary of Movemail Usage + +@smallexample +movemail [@var{option}...] @var{inbox} @var{destfile} [@var{remote-password}] +@end smallexample + +The first argument, @var{inbox}, is the @acronym{url} (@pxref{URL}) of +the source mailbox. The second argument, @var{destfile}, traditionally +means destination file, i.e. the UNIX mailbox to copy messages +to. However, mailutils @command{movemail} extends the meaning of this +parameter. You may actually specify any valid @acronym{url} as +@var{destfile} parameter.@footnote{Rmail does not use this +feature}. Finally, optional third argument is a traditional way of +specifying user passwords for remote (@acronym{POP} or @acronym{IMAP}) +mailboxes. + +Following is the summary of available command line options: + +@table @option +@item --emacs +Output information used by Emacs rmail interface + +@item -p +@itemx --preserve +@itemx --keep-messages +Preserve the source mailbox + +@item -r +@itemx --reverse +Reverse the sorting order + +@item --license +Print GPL license and exit + +@item --external-locker=@var{program} +Use given @var{program} as the external locker program. + +@item --lock-expire-timeout=@var{seconds} +Set number of seconds after which the lock expires + +@item --lock-flags=@var{flags} +Set locker flags. @var{flags} is composed of the following letters: +@samp{E} -- use external locker program @command{dotlock}, +@samp{R} -- retry 10 times if acquiring of the lock failed (see also +@option{--lock-retry-count} below), @samp{T} -- remove stale locks +after 10 minutes (see also @option{--lock-expire-timeout}, +and @samp{P} -- write process @acronym{PID} to the lock file. + +@item --lock-retry-count=@var{number} +Set the maximum number of times to retry acquiring the lockfile + +@item --lock-retry-timeout=@var{seconds} +Set timeout for acquiring the lockfile + +@item -m @var{url} +@itemx --mail-spool @var{URL} +Use specified URL as a mailspool directory + +@item --tls[=@var{bool}] +Enable (default) or disable TLS support + +@end table @page @node readmsg |
