update qdxi_start.pl for SSL email notification

SSL authentication is now a requirement for sending email notifications within a new cloverleaf environment for us.  I am trying to update the qdxi_start.pl script utilized with our cluster failover process to accommodate this new requirement.  I have made the below changes to the script but am receiving the following error.  How do we install perl updates?  how does this affect the cloverleaf install?

Script changes:

$smtp = Net::SMTP->new($host, Hello=>$host, Port=>587, Debug=>1, SSL=>1)

$smtp->auth($smtp_user, $smtp_pass);

error received:

To use SSL please install IO::Socket::SSL with version>=2.007 at E:\cloverleaf\cis19.1\integrator\lib\perl5/Net/SMTP.pm line 67.
