In a contact's view, we want to send messages to all followers of the contact, but not to the contact itself.

When writing a new message, the checkbox with the contact's email address is enabled by default, but we want to disable it.

Is this possible?

Edit: John Baldwin is absolutely right. it could be very dangerous to send a message for internal users to the contact.

Is it possible to disable messages for contacs in general? of course we need messages for other objects, so disabling write/create access for all messages would be not a solution.
