To add a new account, I am entering the email address (*** Email address is removed for privacy ***) and the associated password for that account. But it won't accept it. But curiously, it asks for the ISP password, but the router password isn't accepted, either. I can receive email from the other account, but can't reply to that email; the client operation fails. Not sure what password to use from the ISP.
