Suppose you have two lists: source@example.com and destination@example.com and that you want destination to be subscribed to source. In addition to making destination a member of source (so source sends email to destination), what do you need to put as a non-member in destination?

Should it be 'source@example.com' or 'source-bounces@example.com'?

Email that source sends out has a from address of "source-bounces@..." but is the "-bounces" stripped off before the moderation processing?

Yes, I'm trying to figure out why one particular sub-list isn't getting email.

These questions are answered at https://wiki.list.org/x/4030574 but there's more to it than that.

If source@example.com has only other lists as members, it should be defined as an umbrella list by setting General Options -> umbrella_list to Yes. Without this, one can send a message with

Subject: password address=destination@example.com

to source-request@example.com and the password for destination@example.com will be sent to that list. Setting umbrella_list to Yes will send such notices to destination-owner@example.com, but if the source@example.com list has human members as well, this will mess up notices to them.

Also see https://wiki.list.org/x/4030540 for info about how to use Non-digest options -> regular_include_lists as an alternative.
