Currently, we do have lotus administration as our email server. We have multiple user and group accounts. I say AllEmail is a group account that are members of user1, user2 and user3. The default or primary function of AllEmail group is that when you send here on this email all members will be also sent a copy of the email.
How about only defined users can used the group account? Even so all the users are members of this group account.
Hoping for your help. Thank you.
