Types of List-Server Mailing Lists
Mail that is received by a list-server mailing list and re-sent to the list
subscribers is "posted." Those who can post to a particular list are
determined by the type of list. There are three types of basic
lists. (The list type is set on the Security
tab of the list properties.)
- Open lists (to which anyone can post a
message; the poster need not even subscribe to the
list)
- Subscriber lists (to which only subscribers can post)
- Moderated lists (to which only the list owner can post)
Using Passwords and Posters Lists
The posting of messages to each type of list can be further restricted
by enabling one or both of the following:
- A password requirement (See "Using a Password" on page 174.)
- A posters list
If a password or posters list is enabled, anyone not using the password
and/or listed in the posters list will have their mail returned. The list
owner (or moderator) is also notified at the same time of the attempt
to post.
Note: If there
are only a few individuals who you want to post to the list, you
can simply give those few the appropriate password. However, if there
are more than a few individuals who are to be allowed to post to the
list, it may be more efficient to use a "posters" list.
Open lists (Anyone can post)
The characteristics of an open list are the following:
- Anyone can post to the list by sending a message to an
address in the form of listname@domain.com if Use
Password and Enable Posters List are turned off.
If Use Password is turned on, only those with the password
can post.
If Enable Posters List is turned on, only those in the posters
list can post.
If both Use Password and Enable Posters List are turned on,
the poster must use the password and be in the poster list.
Subscriber Lists
The characteristics of a subscriber list are the following:
- The list is made up of subscribers. An individual becomes a
subscriber by sending a message addressed to the IMail list
server (imailsr
v@domain.com
where domain.com represents
the mail host); in the body of the message, the intended
subscriber enters the subscribe command and the list name.
Subscribers can post by addressing a mail in the form of
listname@domain.com if Use Password and Enable Posters
List are turned off.
If Use Password is turned on, only subscribers with the
password can post.
If Enable Posters List is turned on,
only subscribers in the posters list can post.
If b oth Use Password and Enable Posters List are turned on,
the subscriber must use the password and be in the poster list
in order to post.
Moderated Lists
The characteristics of a moderated list are the following:
- The moderator can post by sending a message to an address in
the form of listname@domain.com if Use Password and
Enable Posters List are turned off.
- If Use Password is turned on, the moderator must enter a
password in order to post to the list. This prevents others from
"impersonating" the moderator by using the moderator's
mailing address.
- If Enable Posters List is turned on, the moderator receives
only mail from those in the posters list.
- If b oth Use Password and Enable Posters List are turned on,
the moderator receives only mail from those in the posters
list, and the moderator must enter a password in order to post
to the list.
