Yes, list.admins may be busy and, yes, EVERYbody should have some form of spam 
protection on their personal computer(s). But since when does that mean that 
list.admins should not worry about whether the server their list is hosted on 
has something like SpamAssassin running on it? 

Unless the end user is always connected to the 'Net and they are running their 
own mail server, all they can really do is signature/hash checking on emails 
they download from their pop3/imap4 server and then delete the ones that show 
a spam or virus signature. But this means in situations like this the user 
will still be receiving 500+ copies a day of the virus. (I have heard from 
some people as high as 3000 over a 48hr perioud.) 500 viral emails at ~150kB 
per virus is ~75,000kB each day and if you are on dial-up that's over 6hrs of 
time required get only your email, so forget about web surfing.

If a server hosting mailing lists runs something similar to 
sendmail+procmail+spamassassin+(razor|dcc) then they could perhaps filter some 
of those copies out. If the major relay mail routers were to all have a 
similar setup along with a few FEATURE(`dnsbl',...) lines in their sendmail.mc 
then they would catch a whole lot more so then the end user would only get 10 
a day. Still annoying, but that's only about 6min download on a dial-up 
connection.

So thus the people who merely shout in response "Install a spam/virus filter 
on your personal computer" are missing the entire point about proactive 
spam/virus protection. Spam/virus protection may begin at home, but it doesn't 
stop there.
