<p>Depends on scale, sophistication of users, and similar other
intangibles.</p>
<p>I have not received a single spam message at one account in
almost 3 years on a long-lived, widely distributed account that
used to receive thousands of spam per day.</p>
<p>Ultimately, it was about taking Paul Graham's _Plan for Spam_ to
the logical extreme: whitelist authorized senders, and quarantine
all other senders (senders can be email, domain, or regex, because
it's in my procmailrc). My quarantine still gets a lot of junk,
but not that much.it turns out it really is mostly (>99%)
junk. A little automation to make whitelist management easier,
along with rebuilding my .procmailrc, and it's been remarkably
effective.<br>
<br>
I have educated a number of users (yes, I still have users) at my
hobby ISP, and they're able to pick up the concepts and efforts
reasonably well. With an average age greater than 80, I expected
more difficulty, but I guess only the hard core folks have stayed
with Free-Net that long.... ;-)<br>

My wife doesn't like it, my kids do okay. Your mileage may vary.<br>

ran my own mail server for several years with spam assassin from
the late 90s into the early 00s. It worked well enough if you
kept up with the ruleset changes and the like. Most of my
handful of users had migrated to other email services around the
time gmail came along. The web UI was light years ahead of any
other web mail provider, and they were great at filtering spam.
I rarely use the web UI anymore in favor of a desktop or mobile
client, so the only thing left for me with my gmail account is
how long I've had it and the spam filtering.</div>

discussed on this list a few times how Google is filtering at
least a few COLUG members' emails to spam without good reason,
and there seems to be no way around it. Now I just found where
Google filtered one of my own emails (not @gmail, but my <a

is registered under my gmail account) -- to spam.</div>

are you guys doing for your email as far as spam and phishing
filtering? Are you doing something yourself server side? Client
side? I've found over and over again in the past (and when it is
turned on by default and I don't realize it) that the filtering
in email clients sucks, and so I always turn it off. Google has
the advantage of bazillions of emails to make a decent guess at
what's spam and what's not. Even with that, they're starting to
suck at it too. I've been left very confused over the last year
or so several times because gmail filters out a single message -
or two - from a COLUG thread.</div>
