Question Is it possible to remove the internal email address option from Customer accounts?

[websavers]

When a customer chooses to edit their profile, they're provided with the option to create an email account on their domain. When they do this, the email account is directly tied to their Plesk account login, so that when they change their mail password, that also changes their Plesk login password.

This is not optimal as it's not clear at any point that changing the mail password will also change the Plesk password. Is there a way to force Plesk to do one of the following:

1. When changing an email password, ensure it does not change the Plesk password
2. When editing a user profile, not provide the option to use internal email (because that's what is forcefully tying the Customer login to a domain-based email account)
