Sender name when commenter gets a message

Hi,

When somebody leaves a comment, they get an email asking them to confirm they want replies.

I notice that the sender name that appears in their ‘From’ field is actually my host admin name and it also identifies which host I’m using.

Isn’t this dangerous? They in effect can go to the login page of my hosting company and already know the username. They would only have to try to brute force just the password and they’d be in.

Is there a way to change the appearance of the ‘From’ field in the message they receive, i.e. who the ‘sender’ is?

Thanks
