Enable individual users to alter their mail settings, thereby overriding the global mail settings that would otherwise apply to them. ‘Mail Settings’ are accessible via their ‘Personal Settings’ or ‘Communication > Mail’. Note: In order for users to be allowed to change their individual mail settings and thereby override the global settings, this needs to be set in the 'Standard Fields' section of the global user account administration settings. If users do not have the permission to change these profile settings, the global default is applied even if users were able to and did change their personal mail settings in the past.
