I decided on Mail::Sendmail. I used CPAN to install and it looks fine. I created a small test program as follows:

#!/usr/bin/perl #
use strict;
use warnings;
use Mail::Sendmail;

%mail = ( To => 'burtonk@chesterfield.gov',
From => 'burtonk@chesterfield.gov',
Subject => 'Test email from Perl',
Message => "This is a test message from PERL !!"
);

sendmail(%mail) or die $Mail::Sendmail::error;

print "OK. Log says:\n", $Mail::Sendmail::log;

exit ;

When I go to run it:

Global symbol "%mail" requires explicit package name at ./emailit.pl line 14.
Global symbol "%mail" requires explicit package name at ./emailit.pl line 20.

What am I missing, the syntax looks fine?
