I seem to recall mentioning the addition of arbitrary headers (though I
attributed it to mail programs and servers).
I mentioned a while ago that I receive most, if not all, messages
on this list with headers like this:
X-Spam-Checker-Version: SpamAssassin 2.60-rc6 (1.208-2003-09-19-exp) on
ms-1.
X-Spam-Status: No, hits=0.0 required=6.0 tests=none autolearn=no
version=2.60-rc6
This ms-1 could also be ms-2, or helios, or circe, etc.
If you look, you'll see that the host at the "on xxxx" bit tends to match
the final rwth-aachen server which passed the message to some server at
your ISP.
Is there a good reason why these headers are allowed to get out and reach
me?
Uh, because that host adds them when performing a spam check. Should it
really be performing a spam check on mail which is is relaying on behalf of
another host at it's own domain? I dunno - but let's face it, at least it
is demonstrating that rwth-aachen is doing something about spam.
Of course that 'RWTH-Aachen.DE' wants us to know that each
message loops'n'hoops through about 7 internal hosts,
[snip]
Yea, looping around doesn't appear to be very efficient (ok, not at all
efficient), but since some of my spam filters key on spammy hosts, I prefer
the full trail approach over the "trim everything up until our list-out
delivery". It wasn't so long ago that the procmail list used to trim the
inbound recevied: headers, and since the list was subject to spamming
(moreso at the time than it has been lately), the procmail list remains in
my filtered list, rather than in my "clean lists" category.
