SBS 2008 Email Distrubition Groups – Permissions

emailwindows-sbs

is it possible to limit the email addresses that use an Email Distribution Email group?

For example:

Person A – Send emails to Group B saying the office is closed due to bad weather.

Group B: Recieves Email

Person B from Group B: Decides to try & email Group B

Ideally we would like to limit the ability to send email to a distribution group, to a certain email address.

Is this possible?
