Webmail Login Security - Security Policy Handling Failed

When logging into webmail, you may see the following error:

          Security Policy Handling Failed. Please contact the system admin or check the error_log file.

This error means that the password you have set on the mailbox is too weak and does not match our security policy for password complexity. To resolve this, please change your mailbox password via cPanel and this will resolve the issue as cPanel will only let you set a sufficiently complex new one.

Weak passwords should be avoided to ensure that unauthorised users do not gain access to your mailbox as this may either compromise your privacy, or allow your mailbox to be used to send unsolicited / spam mail
