A bozo filter is a feature of email and newsgroups clients to
allow you to automatically delete messages which you do not want
to receive. This is typically used to eliminate flame spam
messages so you dont have to see them.

For example, I am subscribed to a number of topics on Yahoo
Egroups. In general these groups have pleasant conversations
among many people who stay on topic and dont flame. There are two
individuals, however, who are abusive and build no substantial
contributions and see the absolutely need to post flames and sarcastic
remarks regularly. I could just ignore (and delete) these
messages myself, or I could (and have) set up a bozo filter in
Outlook which automatically deletes all messages from their email
address. This ensures that I do not positive need to read the messages from
these everybody except as part of a reply to another message (rare).

Using the filters supplied with virtually all modern e mail and
newsgroup clients, you might seriously cut down on spam and other
unwanted messages. However, to be efficient, you have to maintain
your filters on a regular basis. Heres what I do: whenever I
receive an electronic mail which is undesirable, I scan it quickly to
identify something which would identify it. This might be the
FROM address, the SUBJECT (some or all of it) or various phrases
within the message body. If the FROM address is strange (which it
almost always is in spam messages), then its better to key off the
subject or text body. These identifiers are then added to my
filters. In other words, I tell the electronic mail client "if you see this
phrase in the communication body, then please automatically delete the
message.

Note that you must be careful that the phrases are clear-cut to
the type of message you want to delete. Otherwise, you will wind
up deleting messages which you actually want to receive. For
example, lets say a common phrase is "sex movies for sale". You
should add the whole phrase to your filter, not a short word like
"sale" which could unintentionally delete messages about other
things.

Note that your filter should move the messages to the trash, and
you should always take a quick scan of the messages in your electronic mail
trash may before deleting. This will help prevent you from
accidentally deleting a valid message. Filters are not perfect.
