Errors-To: is deprecated as a way of directing NDNs (they should be sent to
the envelope sender of the undelivered item). Almost all MTAs will ignore
it. But I can't see that it should cause any harm as long as you don't rely
on it and also use your administrator address as the envelope sender.
If your provider also insists on some wrong choice for the envelope sender
(such as the list submission address or the posting member's address) and
expect Errors-To: to get NDNs to come to the right place, then you have a
problem. If they let you point both the envelope sender and Errors-To: to
your administrator address, then let the baby have its bottle.
