With a Mailing List, you can set up a discussion forum using an email address where the discussion takes place by email.
Contributions that a list member sends to the mailing list are forwarded to all other members. In an business, for example, important department topics can be discussed by members of that department. You can specify who is allowed to write to the mailing list. A distinction is made between moderators, members and guests.
If a member replies to a contribution in a mailing list, the address of the sender of the original mail is preset. However, the member can change these manually in the mail program. The maximum size of an email that a member sends to a mailing list is 6 MB.
