An email requesting confirmation of your account information purporting to be from the webmaster is a phishing attempt--an attempt to steal your personal information. All such requests from any institution should be ignored.
Thank you to all who alerted me to this attempt. If you are ever doubtful of the legitimacy of an email, please do ask.
If you did take the bait and bite on this particular phishing expedition, change your password immediately. In webmail, the change password option is under options. You need to know that the domain is law in order to change your password. If you notice untoward activity in your account, let us know.
