If you have several teams, and you want to create a group for each of them to send messages separately, create distribution lists and control the mail flow for each one of them. Also using WorldPosta Admin Control Panel, you can grant permissions to a person to send on behalf of any distribution list or accept or reject messages.
A distribution list is a group of mail recipients that is addressed as a single recipient. Distribution lists are used to send an e-mail to groups of people without having to enter each recipient’s individual address. A distribution list is different from an e-mail list in that members cannot reply to the distribution list’s name to send messages to everyone else in the group.
