=head1 NAME

Email::Send::Sendmail - Send Messages using sendmail

=head1 SYNOPSIS

  use Email::Send;

  Email::Send->new({mailer => 'Sendmail'})->send($message);

=head1 DESCRIPTION

This mailer for C<Email::Send> uses C<sendmail> to send a message. It
I<does not> try hard to find the executable. It just calls
C<sendmail> and expects it to be in your path. If that's not the
case, or you want to explicitly define the location of your executable,
alter the C<$Email::Send::Sendmail::SENDMAIL> package variable.

  $Email::Send::Sendmail::SENDMAIL = '/usr/sbin/sendmail';
