=head1 NAME
MT::Mail - Movable Type mail sender
=head1 SYNOPSIS
use MT::Mail;
my %head = ( To => 'foo@bar.com', Subject => 'My Subject' );
my $body = 'This is the body of the message.';
MT::Mail->send(\%head, $body)
or die MT::Mail->errstr;
=head1 DESCRIPTION
I<MT::Mail> is the Movable Type mail-sending interface. It can send mail
through I<sendmail> (in several different default locations), through SMTP,
or through a debugging interface that writes data to STDERR. You can set the
method of sending mail through the F<mt.cfg> file by changing the value for
the I<MailTransfer> setting to one of the following values: C<sendmail>,
C<smtp>, or C<debug>.
If you are using C<sendmail>, I<MT::Mail::send> looks for your I<sendmail>
program in any of the following locations: F</usr/lib/sendmail>,
F</usr/sbin/sendmail>, and F</usr/ucblib/sendmail>. If your I<sendmail> is at
a different location, you can set it using the I<SendMailPath> directive.
If you are using C<smtp>, I<MT::Mail::send> will by default use C<localhost>
as the SMTP server. You can change this by setting the I<SMTPServer>
directive.
=head1 USAGE
=head2 MT::Mail->send(\%headers, $body)
Sends a mail message with the headers I<\%headers> and the message body
I<$body>.
The keys and values in I<\%headers> are passed directly in to the mail
program or server, so you can use any valid mail header names as keys. If
you need to supply a list of header values, specify the hash value as a
reference to a list of the header values. For example:
%headers = ( Bcc => [ 'foo@bar.com', 'baz@quux.com' ] );
If you wish the lines in I<$body> to be wrapped, you should do this yourself;
it will not be done by I<send>.
On success, I<send> returns true; on failure, it returns C<undef>, and the
error message is in C<MT::Mail-E<gt>errstr>.
