Unless you do final delivery on that hypothetical 1U colo box (presumably to
yourself and whoever else you give access to), the mail will almost certainly
acquire at least 1 or 2 more Received: lines while getting to the remote site.
The problem is that some tools run through *all* the Received: headers looking
for borked forward/backward chains or hosts that are in a blacklist. So if
they saw the dialup IP address in one of the earliest Received: lines, you'd
get scored some dings on the spam-o-meter. After all, 95% of any email that
ever passed through a dialup is spam, right? ;)
We now return you to our regularly scheduled episode of "What's wrong with this
picture?"....
