=head1 DESCRIPTION

List the contents of one or more mailboxes.  Specifying more than one
name is only useful when you read in threads, in which case the messages
of both folders are merged.

Options:

=over 4

=item --entities =E<gt> BOOLEAN

(or C<-e>) show the number of MIME-entities in messages. When --threads is
also given, the number is appended to the subject.  Slows down lsmail
significantly since a mail message must be fully parsed to get the entities
information.

=item --size =E<gt> BOOLEAN

(or C<-s>) also show size of message in non-threaded output.

=item --header HEADER-FIELD=PATTERN

only display mails whose HEADER-FIELD (for instance 'subject' or 'from')
contains PATTERN.

=item --nheader HEADER-FIELD=PATTERN

do not display mails whose HEADER-FIELD contains PATTERN.

=item --threads =E<gt> BOOLEAN

(or C<-t> or C<-nothreads> or C<-not>) list the messages in threads.  The
threads are sorted by time: the thread with the oldest starting message comes
first.

=item --help =E<gt> BOOLEAN

(or C<--help> or C<-?>) Print a brief help

=item --verbose =E<gt> BOOLEAN

(or C<--verbose> or C<--noverbose>) Be verbose about the progress of the
program.  This is especially useful for debugging purposes.
