Thank you Wietse, that's what it was. I'd looked (I thought) everywhere
for this, never considered pipe. I had made a provisional maildroprc
solution that effectively did the same by renaming the Delivered-To:
header, but this is obviously the proscribed solution.

To think that I'd been using Delivered-To: headers in all previous PF
versions and the ant-loop never worked, just goes to show ...
