Limit Email accou features

[PersianStar]

Hello,

I'm giving my customers an email account, and the email accounts are made using XMLApi.

After their email is made, they can login using domain.com:2095, there they have some abilities such as: "Change Password", Forwarding Options, Auto Responders, Configure Mail Client, Email Filtering, Email Trace and also they can select if they want to use "RoundCube", or "Horde" and also "SquirrelMail".

I don't want to let them see these settings, the only thing they should access to is "Change Password", the rest of options there are unnecessary and proffered to be not shown there. also "RoundCube" should be there only.

So just "Change Password" and "RoundCube" in that page!

How I could achieve these settings?

Kind regards,

Any answers for this?
