I use a whole different approach:
1. make 2 Email accounts. (one for web, and one for personal).
2. create a folder for REAL inbox.
3. make message rules.. if messages contain people (your personal email
address) move all messages to (REAL inbox).. if messages contain people (web
email address) then DELETE messages..
Now, us the WEB email for newsgroups, companies that REQUIRE you submit a
valid Email address, untrusted people, IRC's and other Web stuff.. and the
personal for friends, family, and trusted people.. This way all your real
messages are in your REAL inbox, your spam is deleted, and the forged
headers are in the inbox ready for deleting, and if you need to get a serial
number (emailed to you) look in the trash and dig it out.
If there was a 'if TO line DOES NOT contain (your personal email address)'
message rule setting available, you can keep the inbox for good messages,
the spam deleted, and forged headers deleted.
This is the best way I found to sort all the spam I get.
Hope this works for people
