Ok, i'll explain better.
In other Mail Server Software (like Kerio Connect, MS Exchange, MailEnable, Zimbra and so on...) there's a funtion aside users/mailboxes called:
- Distribution Groups (MS Exchange)
- Groups (Kerio Connect)
- Groups (MailEnable)
- Distribution Lists (Zimbra)
and so on...
These objects are a sort of "virtual e-mail address" that wil be delivered tom 1 or many real users/mailboxes
Ex.: a mail to "info@xxx.yyy" will deliver a copy of the message to "paul.young@xxx.yyy" and a copy to "tony.white@xxx.yyy".
Nothing will remain in "info@xxx.yyy" because that mailbox doesn't really exist.
This kind of objects can only be managed by administrators in the administration console.
The users cannot subscribe or unsubscribe themselves (so it's not a "mailinglist")
This objects doesn't consume licenses because they are not a real mailbox/user.
You can think of that also like a sort of "single mail address alias" that will be delivered to multiple users.
