Not yet. I'm still waiting for the pony I put a request in for months
ago. :)
Yes, my example was a bit extreme. I was merely trying to make the
point that SPAM filtering (regardless of whether the destination is an
individual or a list of individuals, it makes no difference) can be
done
using heuristics other than white lists.
Filtering spam is likely one of the better points of the software we
have on hand as between the postfix rbls and the spamassassin rule
sets, we punt about 60-95% of all mail coming at the system on any
given day. The thing is that user/subscriber/whitelist management
across 300+ lists is not something simply done in the current model
and wildcards leave holes the size of small countries through which
anyone with sendmail and a little, a very little, knowledge could
drive anything they wanted through. I'd be happy to demonstrate this
for anyone who doubts how easily mail can be spoofed.
