I agree that this isn't going to be the best approach. Detecting ham
is simply more difficult:
1. New types of ham emerge more often than new types of spam. Spammers
generally stick to tried-and-true subjects while ham is all over the
place.
2. Ham is more personalized than spam. Everyone gets

One consideration is that spam getting through is never more than an
annoyance. Ham getting caught can be a big problem. So any kind of deny

mail that gets trapped and provide a way for the sender to get
approval. How
This would be easier to filter.
It would also be more adaptive to a statistical approach than a regex

Clarifications:
1) I'm not talking about generating new rules. Rules stay the same.
I'm describing a new scoring process only.
2) This would not be a replacement to SA, but an improvement. Just a
new way to process results already generated by SA. Ideally, this

Is that the same as whitelisting, maybe I do not understand, but a very
rigorous approach would
be a whitelist methodology which, once a new account is created, they
send email to everyone they
want to communicate with, and it 'autowhitelists' those addresses, so
you can only receive from those

Good point, but will cause trouble UNLESS we find a way to recognize

As other users said, with current system, if we can filter 70-80 of the
