Thank you, Marc.

Additionally, and with a bit more details, the reason

     " The message headers matched a filter rule "

is really from the very last filter bank, which is 'mailman' and
to answer Bert's question wrt that: No, nor the mailman setup,
nor the R-help specific extra filters have changed during the
last months, probably not even during the last years.

The mailman filters however *do* look at some of the upstream
spam filter results (most of which are ETH wide), and these do
change of course, continually being adapted.
