is the from address:
"fromAddress" => "sales@franksproduce.net",
you are using a valid address for you domain?
Blue host is very strict that the from address must be a valid from address fro your domain.
also, try changing this ine:
$WA_MailObject = WA_SecurityAssist_Definition("box688.bluehost.com","465","","","","");
to:
$WA_MailObject = WA_SecurityAssist_Definition("","","","","","");
to force the script to use the smtp server and port from the php.ini.
Are you testing this locally?
the blue host smtp servers will not allow connections from outside servers.
