For those on the list who don't follow -private, it was something to the
effect of:
When a new mail comes in:
if from/sender is a subscriber:
send it on
if from/sender is in whitelist:
send it on
otherwise:
store message for up to 48 hours
send challenge to from/sender
[ if valid response is received:
add from/sender to whitelist
send message
]
The challenge/response should probably be the same sort of thing you get
for subscriptions. This'd allow people who send mail from an address
other than what they subscribe from to cope fairly easily, as long as
they're posting from a real address (or can add the appropriate headers
to point to a real address).
Adding a blacklist, or making it "subscriber to any debian.org list", or
making the challenge/response require more intelligence, or making a single
response work for all the stored messages from that person, would also be
options.
Cheers,
aj, idly pondering doing something similar for his personal mail...
