Its the same provider i use to send emails to all lists so why no
others get "spammed", i have no idea. I didn;t realise that your own
provider tags sent emails as spam, i thought it was done on receipt of
an email.

Spam scoring & tagging is often done at the recipient's MTA, but there's
no reason it can't be done at other stages as email gets relayed between
machines. There's obviously a trust issue (rogue senders could spoof the
spam-scoring as well) so in most environments only the last hop counts,
and that helps with lightweight/mobile clients too.

I guess as BT is a large ISP with a variable community of users they may
be testing "outbound" mail to try and prevent some abuses escaping their
network and damaging their reputation?

BT seems to have done this for a long while with your outbound postings,
and you typically seem to score 8-10/50 when sending :) I expect your
local/last-hop-inbound spam categorisers have changed a ruleset recently
which is why your mail was marked as SPAM locally to you. You'll need to
inspect the headers on the received message on your machine, as when
your reply goes back out to the list and is received <everywhere else>
then whatever is running <everywhere else> will have overwritten the
X-Spam-.... tags locally (or been stripped en-route).

For example, your mail tagged as "[SPAM]" sent back to the list only
scored -2.5 for me, with a required of 5.0, scored by SpamAssassin.

If you are doing Bayesian filtering, when was the last time you trained
your local categoriser with recent ham, as well as spam?

In this case, his own possible filtering is not involved at all: it is the oubound email sent to the list which got tagged somewhere "en route". It could be at his ISP or at another server. Not the ones at opensuse.org because we know there is no such kind of filtering that modifies the subject line.
