Archive Messages to Enable Merge Mailings

This option determines whether messages sent to this mailing list will be saved in the archives. Saving a message in the archives allows it to be read at a later date.

Not saving archives conserves disk space.

Note: If you disable archive saving, users will no longer be able to receive digest versions of the mailing list, and ListManager will be unable to check for duplicate messages. You will also not be able to purge message recipients later, or create segments based on those who click on clickthrough or clickstream tracking URLs.

If you want your users to be able to receive digests or for duplicate postings to be purged, but do not want to keep archives, set the Save Archives setting to "YES" and set the Archive Days setting to "1" in Utilities: List Settings: Automatic Maintenance: Purging Archives.

Save Recipient Info to Enable Purge Mailings

This option determines whether information about which recipients received a particular message is saved with archived messages. If you are keeping archives and you have this setting enabled, the member ID of each recipient will be saved with the archived message. Those recipients may later be purged from other mailings.

If messages are not archived, recipient info will not be kept.

Saving recipient info is necessary if you plan on purging recipients in Mailings: New Mailing: Recipients.

Enable This List as a Child List

This setting determines if this mailing list will accept message submitted directly from another mailing list.

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, these lists could be in a parent/child relationship:

sports-announcements
soccer-announcements
tennis-announcements

If lists are set up in a parent-child relationship, messages you send to "sports-announcements" can be sent to members of "soccer-announcements" and "tennis-announcements" automatically. 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 would create any ordinary lists (you will later establish the parent-child relation between them). You should not use message wrapping in any list that will act as a parent, as these header/footers will be reproduced when the messages are posted to the children.

Set each list (except for the top-level parent) to have Enable This List as a Child List set to Yes, and also the have Cross-postings and Duplicates in Utilities: List Settings: Discussion Group Features: Message Rejection Rules: Same Message Rules set to have multiple copies of cross-postings removed. This 2nd setting is important, as it instructs ListManager to make sure that people who are members of multiple lists only receive one copy of a message sent to parent/child lists.

Both lists must keep archives for at least one day for ListManager to purge duplicate messages.

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 message wrapping in the parent, and 2) the messages are at least 240 characters long.
