It smelled like a philosophical discussion more than anything else.
After a more than a year using SA I have a lot of confidence in
it and I now use a milter to delete messages with very high SA
scores outright so I don't think it would be a "bad" feature to
implement "delete" within SA. Not a big deal though .....
I guess it is a little philosophical, but given that the user has the
ability to delete based on level and the fact that it can take some time
to train it correctly it is probably the best option not to delete
automatically.
If they did implement that as a feature then they would need an option
to disable it for those that are in the process of training it or just
paranoid that a false positive may occur.
I have found that after the first few weeks of training and setting up
my whitelist that I have had no false positives in well over a year and
a half.

I've been pretty impressed with greylisting too. It cleaned up many
of those pesky spam mails that SA didn't catch and many more that
SA could catch and spent time analyzing, really easing SA's work
load.
When I first setup greylisting I was not expecting such a dramatic
impact on the level of spam I had been processing. It literally dropped
from 3000 to 6000 spam messages a day down to 4 to 8 a day (which
spamassassin took care of). Just shows how many zombie systems are
being used for spam out there.
