Won't work with GoDaddy, TCP port in the URL causing the problem?

[paulstaf]

Here is my URL:

https://a2plcpnl0337.prod.iad2.secureserver.net:2096/cpsess12345678/3rdparty/roundcube/?_task=mail&_action=compose&_to={to}

If I remove the ":2096" (TCP port), or just remove the colon (:) then it will accept it and put it in the list of email services. Otherwise it will accept it, but it won't put it as the default email service. Obviously the link won't work without the TCP port. I have tried all kinds of "escaping" the colon, but can't get it to work.

Any ideas?
