Child List
This setting determines if this mailing list will accept message submitted directly from another mailing list. By default, Lyris List Manager 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" and 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 List Manager 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.
If you have configured the lists to reject cross-posted duplicates, you will prevent members of multiple child lists from getting many copies when a message is sent via the parent list. However, this
feature will only work if : 1) you do not include mail-merged footers in the parent, and 2) the messages are at least 240 characters long.
