Third, my recipes are better than SA. Without significant tuning,
SA gives me lots of false pozzes, and a few false negs. My recipes
are simply more accurate.
I just have to agree with you on this one... although, I do kind of base my
spamfiltering around DCC, meaning that anything I catch I report as many, and
then act upon that many-value.
Maybe you think of that as cheating, but nevertheless I've had much better
results with this than with SA; and I don't have to worry about SA falsly
catching a friends e-mail simply because he sent me a dirty joke and/or
forwarded spam that he thought was funny.
Fourth, and I've saved the best for last: SA is a HOG. I refuse to
fire up perl for each message,
Well, there is the spamc and spamd-option.
and I refuse to full-body-grep each
message that comes in. That is the same philosophy that spawns all
bloatware. In my quest to do better than SA on my own, I use
*essentially no* body greps. I find that I can consistently
catch 99.7% of spam, with very few false pozzes, using only
header matches. I don't even look for $$$$$$$ or !!!!!!! or
"FREE!!!" in the Subject:. Not that it's not a useful check; but
I just don't need it. The spam gives itself away by characteristics,
so I rarely need to rely on specific choices of spammy words.
My recipes are lean and mean. I can check and recheck batches
of spam at little cost. One hundred at a time running through
my full rc, with log writes to /dev/tty, happen in 20 seconds.
I think I must be at about 100 times more efficient than SA.
SA is useful. I use it as a tool to help me tune my recipes. But
I don't want to rely on it. I'd rather be in full personal control
of what happens to my mail.
It's used serverwide, and looking at what I catch and SA catches I'm doing
much better without filtering based on SA.
