* Before setup, please try to login WebMail once, to make sure your email address and password are correct!
* If connection failed, but it ask for password, it means your password is wrong.
* If connection failed, but it does not ask for password, it means it is a connection problem, please try other connection methods (SSL/STARTTLS/No-SSL, etc)

=== Why are there so many connection methods? Which one should I use? 
* Most people should try the SSL/TLS connection first. This method should work for 99% of modern devices.
* Some country/state/company firewall blocked one or the other ports. Some software/device/versions has bug in one or the other connection methods. That's why people invented different workaround methods. Please try other methods if SSL does not work for you.
