Ah! You are talking about deliveries created by the Exim system filter, not

You should not be using deliveries created by a system filter for
mailing lists. Or indeed for any "normal" deliveries.

The purpose is to record the original recipients of the message when a
system filter creates additional (or replacements) deliveries, that is,
if it overrides or supplements the original recipients list. These are
not "normal" deliveries.
