Common Problems
- Before setup, please try to login WebMail once, just to make sure your email address and password are correct!
- If error message was shown, please try to read it, or send it to us.
- If connection failed, but it ask for password, it means your password is wrong. (use copy-and-paste, do not type)
- If connection failed, but it does not ask for password, it means it is a connection problem, please try the other connection method (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.
