If your site was already using SellOnline, you can simply replace the /includes/modules/shipping/canadapost.php file found in the updated plugin zip at: https://www.zen-cart.com/downloads.php?do=file&id=4 (ie: you don't need to touch the other files)

You can also tell your hosting company that they no longer need to open TCP port 30000 on your firewall (if you made a special request for them to open it).
Thank-you so much for the update. I dropped the new file in like you instructed and it worked perfectly. I didn't need to contact my web host at all.
