Mail::Transport::Sendmail - transmit messages using external Sendmail program

=head1 CLASS INHERITANCE

 Mail::Transport::Sendmail
   is a Mail::Transport::Send
   is a Mail::Transport
   is a Mail::Reporter

=head1 SYNOPSIS

 my $sender = Mail::Transport::Sendmail->new(...);
 $sender->send($message);

=head1 DESCRIPTION

Implements mail transport using the external C<'Sendmail'> program.
When instantiated, the mailer will look for the binary in specific system
directories, and the first version found is taken.

Some people use Postfix as MTA.  Postfix can be installed as replacement
for Sendmail: is provides a program with the same name and options.  So,
this module supports postfix as well.
