but how well does the IETF do in not producing email in response to SPAM?
Seems the IETF generates a lot of backscatter, and aside from scattering this
to individual boxes all over the Internet, it's going to scatter into various
spam traps… and that's likely to cause a listing in any services that use
spam traps. Those who implement spam traps do put filters on them, so that
commonly produced bounces don't cause listing, but it's had to deal with the
many custom bounce messages (especially ones which don't use standard headers
to indicate they are auto-generated).
Has anyone examined all the various sorts of auto-generated messages the IETF
produces to make sure they are reasonably detected as auto-generated messages?
That should be part of us doing our part to help deal with SPAM.
I watch all the bounces for about half a dozen of the high traffic lists.
One of the more annoying things I see is bounces from subscribed members due to
the sender being listed somewhere. when this happens with frequency those
particapants that bounce messages to mailman get ejects from the list... We
don't have the luxury of just ejecting someone from list because the source ip
they are using today is listed in spamhaus but if you recject enough mail from
us you're going to fall off.
Honestly I think the backscatter is frankly rather low as a purportion of net
volume but the volume is large.
A busy day on the ietf discuss list bursts out to a few hundred thousand
messages however, for a single list.
