How the subscription list works.
The Mailing List is basically a discussion forum using an email address where the discussion takes place by email.
Contributions that a list member sends to the mailing list address (firstname.lastname@example.org) are forwarded to all other members.
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.
