[amsat-bb] Spam through amsat.org

[Phil Karn]

A significant fraction of the spam I get on my primary email account
comes by way of the amsat.org email reflector; by my count, 18 of the 76
spam emails I've received in the last day.

But I don't want to just shut it off; sometimes people I do want to hear
from make contact that way. And I've used it to contact others whose
email addresses I don't know, but who I know to be AMSAT members.

I wonder if it would be possible to set up some sort of auto-responder
on amsat.org so that instead of just forwarding email, returns a message
to the sender with a non-machine-readable image of the user's actual
email address, possibly accompanied with a sound file with the same
information for anyone with impaired vision. Spammers couldn't handle
it, especially since most don't even use valid return addresses. But any
real human could resend his email directly to its destination.

What do people think of this idea? How much of a problem is spam for
everyone else here?
