We have implemented SmarterMail minimum password requirement on all global mail server setting, which requires each POP3 account password to have the following requirement.
1. The password must have at least a minimum of 5 characters.
2. The password should not be equivalent to the POP3 username.
3. The password should contain at least a minimum of 1 symbol and 1 number. Infact should be combination of Alpha + number + symbol
The above is applied as a security precautions to prevent any of the POP3 user account from being hijacked by malicious user due to easily guess password.
User will be required to login to the webmail or login via the Helm control panel to update the POP3 user account password.
