The Lampe domain (aceryder.com ... Named by Trevor), is home to
around 75 email addresses over 5 domains.  By late 2004, we were
receiving, on average, about 2000 pieces of spam email per day.

In early 2005, we implemented a 2-tier spam strategy which included
Grey/White/Black-listing (see http://www.greylisting.org/ for more
information).  In a nutshell, a whitelist is a list of Internet 
addresses which are either trusted or have shown themselves to
be a valid, non-spamming, SMTP server.  A blacklist is a list of
Internet addresses which are known to be spammers.  There are many
Realtime Black Lists (RBLs) which can be automatically downloaded
and inserted into your specific blacklist.  A short list of RBL
sites can be found at http://www.openbsd.org/spamd/.  And, finally,
a greylist is an unknown site which is currently being 'put on hold'.
That is, when our email server is connected to from a non-whitelist and
non-blacklist server, we tell the server that our email service is 
currently unavailable, please come back later.  Now, a valid email
will retry over the course of a few days.  A spam email will typically
just go away :-) .  

After implementing the Grey/White/Black-listing, we instantly killed
95% of all the spam coming into our servers.  That's nice.  For the
other 4.9%, we migrated from Microsoft Outlook to Mozilla Thunderbird
as an email client.  Thunderbird comes, default, with a 'Junk mail' 
filter.  It took a few weeks to train the Thunderbird (as simple as
clicking a 'junk' icon when junk mail is received and unclicking the
junk icon when it incorrectly categorizes valid email as junk).  After
the training was complete, we eliminated that other 4.9% of spam.  

We still get the occasional spam email.  But, it's less than once a month
(for me anyway).  Email is now useable again.  

For more information, see the links above.  Or, if you're a friend or family
member, shoot me an email and I'll either help you out or give you an email
account on my 99.9%-spam-free server ;-)
