We get frequent requests for this from our customers (as well as ourselves, being an ISP). Ideally, multiple options would be nice. Example, 1, only disallow the user access to the account and continue to accept mail for it, and 2, disallow access and reject mail for it. If it can only be implemented one way, the latter is preferred. Having to completely delete the account is disadventageous.

I hope the CP devs will consider this.

Thanks
