This library should run on perls released even a long time ago. It should work on any version of perl
released in the last five years.
Although it may work on older versions of perl, no guarantee is made that the minimum required version
will not be increased. The version may be increased for any reason, and there is no promise that patches
will be accepted to lower the minimum required perl.
DESCRIPTION
This transport sends mail by piping it to the sendmail command. If the location of the sendmail command
is not provided in the constructor (see below) then the library will look for an executable file called
sendmail in the path.
To specify the location of sendmail:
my $sender = Email::Sender::Transport::Sendmail->new({ sendmail => $path });
