Public bug reported:

If a post is addressed to multiple lists, say list1 and list2, and list2 is in list1's regular_exclude_lists, and list1's regular_exclude_ignore is Yes, and the poster is not a member of list2 but the post will be accepted by list2 because of list2's equivalent_domains setting, the regular members of list1 and list2 will receive the post from both lists.

For a more concrete example, consider a post to list1 and list2 from user@mac.com. user@mac.com is not a member of list2, but user@me.com is a member of list2 and list2's equivalent_domains includes "mac.com,me.com", In this case, if list2 is in list1's regular_exclude_lists, and list1's regular_exclude_ignore is Yes, regular members of both lists will receive the post from both lists and not be excluded from receiving the post from list1
