[BC] If you wonder why email is getting worse

Interesting comments! I'm currently using spamcop.net to refuse
connections from machines identifed as spammers (in the sendmail config).
But, the idea of scoring and using that along with SpamAssassin sounds
interesting. It SEEMS that a way to reduce false positives would be to
automatically generate a white list from someone's address book. Or,
perhaps analyze outgoing mail and accept mail (or put a big negative score
on its spaminess) if this particular user has sent email to this
particular address (perhaps dropping addresses from the list if they have
not been used in a while). That analysis of outgoing mail seems simpler
than requiring users to upload a whitelist. I see, though, that Mozilla
Thunderbird has an option to not mark stuff as junque if the sender is in
your address book. So, maybe this will handle it for Thunderbird users. I
need to get something like that going on SquirrelMail, though I think I
have very few false positives.
