If spam is the problem, a better mail server can be the solution.
Running your own mail server isn't nearly as complicated as it used to be.
QmailToaster (http://wiki.qmailtoaster.com) with spamdyke is a very good
combination. Spamdyke rejects 90+% of spam without even receiving (or
scanning) the message. The sanesecurity extensions to clamav catch the
lion's share of phishing attempts. With this setup, I get <1 spam per day.
Disclaimer: I'm presently the project lead for QmailToaster.

I don't remember the url, but a few years ago I found a site that had an
interesting idea to fight those who try to con people into handing over
account information. If you got one of these scam emaills, you would
submit the url the phishers included. Their system would generate
random strings of text and submit these to the phishing site over and
over again. The result being the phishers would have lots of bogus
account data and would waste their time trying it.

As I remember (but remember whose memory we are talking about :-) -
I had 3 lists - those known to be spammers, those known to be ok, and
anybody else. (Ok, so the 'anybody else' wasn't actually a LIST, it was
anybody not in the first 2 lists)
Known spammers got some huge delay (I think I finally ended up with 24
hours!), known safe senders got zero delay, and unknown got a few
seconds (or maybe I made it zero, I don't remember).
So non spammers got either zero or minimal delay.
If I can remember, I'll see if I still have that config file somewhere,
cause now you got me curious!
I should mention that there IS one 'small' downside - if you get ALL
your internet sockets tied up with spammers then you cannot receive (or
send) email (or do anything else network-related until one of the
sockets frees up). I don't think I ever hit that limit, but then I only
do email for my family...

Rusty, how did tarpit and that delay time effect non spam users?

I've tried running that thing that keeps spammers busy trying to
deliver the email (tarpit? I cannot remember - the idea is you keep
telling unknown MTAs 'hold on a moment' for a while - say an hour or
more, thus keeping their delivery rate low. I should mention that at
home I run my own MTA, so it was an option for me. Anybody using
their
ISP's MTA (or gmail, or...) cannot do this). The problem is that you
need a LOT of people running that for it to do much good in spam
reduction overall, and I don't' know if it reduced mine (but it was
satisfying to look at the headers and see that couple of hour delay).
