Accounts4Fixer: Alternative tool for Mail.app account settings panel.
THIS APPLICATION DIRECTLY MODIFIED
~/Library/Accounts/Accounts4.sqlite DATABASE. YOU SHOULD NOT USE THIS TOOL IF YOU ARE NOT FAMILIAR WITH IT.
Mail.app on macOS High Sierra(at least up to 10.13.6) has a bug that it cannot accept 'Allow insecure authentication' enabled settings.
The Mail.app tries to check whether newly entered authentication information is valid or not before saving the setting values, but if the server does not support 'SSL' connection, the app fails to this validation, and it prevents to save the information.
This application allows you to set some properties for Mail.app settings.
