As far as I know, every MTA that adds a Delivered-To: header records an internal
version of the address and uses it for loop detection.

If you know of MTAs that add the header but don't use it for loop detection, I'd be interested
to hear about it.

I know of MTAs such as Exim that add a different header with an envelope address, but not Delivered-To.
