This setting determines if this mailing list will accept
message submitted directly from another mailing list. By default, Lyris rejects
messages sent from other mailing lists, and this setting overrides that
default.
This option is used to create
parent/child mailing lists, where sending mail to a parent list automatically
sends to a child mailing list.
A typical scenario for setting up
parent/child list is if you have multiple announcement lists, and they are
related in this way. For example, if you have these lists:
sports-announcements
soccer-announcements
tennis-announcements
these are logically in a parent/child relationship. If you
send to "sports-announcements", you want the members of
"soccer-announcements" and "tennis-announcements" to get
the message. Or, you may just want to send to "tennis-announcements"
and not to any other list.
Here are the instructions for
setting up a parent/child list. Please follow these directions carefully, as
the relationship is a little difficult to grasp:
1) first, create your parent and
child lists as you normally would. You should not use headers or footers in any
list that will act as a parent, as these header/footers will be reproduced when
the messages are posted to the children, and this can be confusing. Set each
list (except for the top-level parent) to have "Child: yes" set, and
also the have "Remove duplicate members: yes" set. This 2nd setting
is important, as it instructs Lyris to make sure that people who are members of
multiple lists only receive one copy of a message sent to parent/child lists.
2) decide who should be able to
post to your mailing lists, and make them a member of all the lists (parents
and children) that their message should be distributable to. A person has to be
a member of the parent, and all its children in order for the message to be
distributed. You should also set the security permissions for this person so
that their post goes through the security tests you decide. For instance, you
may want to allow any post from the person to automatically be approved, in
which case making this member a list admin on the lists is best.
3) In each list that is to serve as
a parent list, subscribe the child list's posting address as a member of the
parent list. For example, you would create two members in
"sports-announcements", with the email addresses
"soccer-announcements@yourserver.com" and
"tennis-announcements@yourserver.com". Child lists can also act as
parents to other lists, so you can nest the parent/child relationship as deeply
as you like.
