VyprVPN has blocked port 80. They say it is to do with too much SPAM going through their system. They told me to use port 587 or port 465 in my Mozilla Thunderbird email. I have tried to change the ports and then send messages but I get error messages when I use Thunderbird using either of those ports. It plain just doesn't work. My emails are encrypted only for incoming but not for outgoing. I have also tried turning off my Firewall and Antivirus. It made no difference.
