A fair proportion of my spam comes from debian.org addresses; spammers
are becoming more adept at forging sender addresses, frequently by
pulling addresses from e.g. web pages and using one address as the
source and the others as the target, so the recipients are likely to
know the alleged sender.
I predict that challenge-response systems will become increasingly less
useful as time goes on due to this trend.
