E-postlister - Generell innføring

Hva er en e-postliste?

A mailing list is a distribution list allowing a group of subscribers to automatically receive by email all messages sent to the list: every message sent to the list by a subscriber is received by all the other subscribers. When subscribed to a mailing list, it is possible to send messages, to reply to them or to read them without contributing (i.e. to "lurk").

Folk abonnerer på en e-postliste (noen ganger forkortet til ML) for å bli informert om et bestemt emne ta del i diskusjon rundt det. Eksempler er:

Listmasters are in charge of the management of the mailing list service. Their duties:

List owners and moderators can turn to listmasters when they face a problem not dealt with by the documentation or for any comment. However, in order not to flood listmasters with messages, it is recommended that subscribers rather turn to list owners.


The list owner is generally its creator or, failing him/her, the person who requested the list creation or who became responsible for it. His/her role:

A list can have several owners. However, the 'Privileged' profile is reserved to the list's creator; other owners have a 'Normal' profile, which has fewer prerogatives.


Moderators are appointed by the list owner. They are in charge of controlling the relevancy of the messages sent to the list: after reading them, they choose to accept or to reject them . Moderation occurs before the message is actually sent to subscribers. Rejection of a message is possibly followed by a notice to the sender in order to explain the reason for that rejection.

A list can have one or several moderators; generally, the list owner is also a moderator.

This concerns only moderated lists.
