Connectivity tests always fail?

1. the default name for outgoing mail server should be changed from http://www.googleapis.com to smtp.gmail.com

2. The tests for status on ports 25, 465 and 587 will always fail since portquiz does not support these:
http://portquiz.net:25
http://portquiz.net:465
http://portquiz.net:587

3. The Service Available fails too, even though ports 25, 465 and 587 are indeed open
