Well, there is a string "Error sending email {0}" and it's good, as you can search for actual error in Error.log.
When I have had problems with sending emails there was no error, Send function just stuck.
Also, I definitely have to remove "Domain": "bounz.net" I've used while investigating my own email problems. I'll post corrected binaries today evening.
About "SSL" checkmark in the "email account": I have set it up and it has been successfully saved. Have you pressed "Reload" (something like that) button in the popup with email settings?
