Commit 7cbbb401 7cbbb4012d63c86e8e0726a5634bdd880ffe34b3 by Sergey Poznyakoff
Options

Movemail improved. 

* movemail/movemail.c: New options: --ignore-errors and --program-id.
(_compare_msgno): Remove now unneded static.
(main): Handle --ignore-errors and --program-id settings.
Optimize the main loop for the case when --uidls is given.
Return 1 on errors.
* doc/texinfo/programs.texi: Document new features.

@deffn {Movemail Config} ignore-erros @var{bool}
Continue moving messages after errors. By default,
@command{mailfromd} exits immediately if it cannot copy a message.
@end deffn
@deffn {Movemail Config} program-id @var{fmt}
Set program identifier, i.e. a string which will prefix all
diagnostic messages issued by the program. By default, program
name is used.
The @var{fmt} is a format string that may contain references to the
following macro variables (@FIXME-pxref{macro-variables}):
@table @code
@item progname
The program name.
@item source
URL of the source mailbox.
@item source:user
User part of the source mailbox URL.
@item source:host
Host part of the source mailbox URL.
@item source:path
Path part of the source mailbox URL.
@item dest
URL of the destination mailbox
@item dest:user
User part of the destination mailbox URL.
@item dest:host
Host part of the destination mailbox URL.
@item dest:path
Path part of the destination mailbox URL.
@end table
Setting @code{program-id} may be necessary if several @code{movemail}
instances are run simultaneously (e.g. invoked from a script) to
discern between the instances. For example:
@smallexample
program-id "$@{progname@}: $@{source@} => $@{dest@}"
@end smallexample
@end deffn
@deffn {Movemail Config} uidl @var{bool}
Avoid copying the message if a message with the same UIDL already
exists in the destination mailbox.
