Don't you see the difference yourself? The news software which
makes the decision not to send an article to a site doesn't
know about domains. It just does a strcmp on stuff between '!'s.
"blia" and "blia.UUCP" are therefore not equal, and you get the
article back.

Absolutely not! Rejecting an article because it's in the history file
requires you to receive it first, which means you would have to spend
megabucks to get back a full newsfeed of stuff you'd just sent to each
neighbour, only to decide that you already have it. That's why inews
will decline to send an article to any site which appears in the
Path: line.

As stated before, the fix is for all moderators to make sure nothing
containing mailing information appears in the Path: line.  Please!
