Thanks Mark,
It's not spam, but a bilingual German & English change of address,
presumably from an auto responder from a subscribed address (I checked).
as per

Which I assume it got from list header of previous post to list:
	Errors-to: gea-chat-bounces at mailman.berklix.org
	Sender: "Gea-chat" <gea-chat-bounces at mailman.berklix.org>

OK, I accept that spam filtering is best left to other tools,
but this is not spam, but an auto responce from a subscribed address,
so if mailman could recognise it automaticaly it would be nice.

Thanks. At berklix.org I have no time for subscribers who consume
list owners' time with auto responders, I like mailman to auto
detect automatic response noise, & count & auto unsubscribe continuing
noisy subscrbers.

In case the sample is of use I will leave it here for a bit:
