|This depends on the email client you are using (the program you use to read
your mail). If it has a junk mail filtering capability then enable it (after reading the
documentation on it). If not does your client allow you to setup some filters to discard
Don't expect 100% filtering of spam. There are two aspects to spam filtering, false positives
and false negatives. A false positive is where a legitimate piece of mail is deemed spam, a
false negative is where a piece of spam is not detected as such. False positives are, IMHO, far
worse than false negatives.
The email client I use (Poco) has a junk mail filtering capability. I've tuned it to a great
exent. Before Christmas (2001) I had a false negative rate of about 25% and a false positive rate of
near 0 (I only recall ever having one false positive). The false negative rate has gone up
since Christmas, some spammers must have gotten new toys and I haven't fully updated my filters
yet. Today I had a false negative rate of about 45% but I did update my filters and hopefully
that will decrease in the days ahead.
Since this time my ISP has started running Spam Assassin. In addition I've been fairly rigorous in keeping
my junk body text file up to date and have taken advantage of Poco 3's ability to seed
the junk mail score. My recent spam detection rates have risen to above 98%.
