They could also select every address from the GAL without too much trouble, even if you didn't have an EVERYONE DL. The only way you can stop this is to limit the maximun number of receipients per message on the Message Delivery / Defaults tab, and then assign those who are allowed to E-mail everyone a higher limit in ADU&C - Exchange General / Delivery Options button.

It will only accept message from testaccnt username. This will prevent other user to use the EVERYONE distribution list to send messge to everyone, when the userr received the mail and reply on the mail and expand the EVERYONE distribution, the EVERYONE distribution list will be treated as individual mail so they can still send message to everyone. My question is thier a way where i can disable sending mail to everyone one even they expand the everyone distribution list or disable expanding the everyone distribution list ?
