=head1 NAME
Email::Sender::Transport::Maildir - deliver mail to a maildir on disk
=head1 VERSION
version 1.300010
=head1 DESCRIPTION
This transport delivers into a maildir. The maildir's location may be given as
the F<dir> argument to the constructor, and defaults to F<Maildir> in the
current directory (at the time of transport initialization).
If the directory does not exist, it will be created.
By default, three headers will be added:
* X-Email-Sender-From - the envelope sender
* X-Email-Sender-To - the envelope recipients (one header per rcpt)
* Lines - the number of lines in the body
These can be controlled with the C<add_lines_header> and
C<add_envelope_headers> constructor arguments.
The L<Email::Sender::Success> object returned on success has a C<filename>
method that returns the filename to which the message was delivered.
