We have a few big old lists, which we may use some day and I don't want to remove them for now, but at the same time I don't want when importing new leads duplicate checker to leave out leads, because they already exist in the old lists. We almost always need to use 'check for duplicates in entire system'.
Searching for 'active' in listloader_super.pl and listloader.pl gives me no result, are non-active lists used as well for the duplicate check?
How can I make it only the active lists to be used instead?
