Let me explain a couple of things to you.
1. When you're reading newsgroups, be sure to check where you're posting,
and to eliminate any places that you feel are not relevant.  This helps
cut down on spam.

2. When people send you junk mail, they alter their "From:" and
"Reply-To:" addresses to point to nothing.  That's why you get the "This
address does not exist" messages.  Instead you have to do a bit of
detective work to find out the proper address.  The first thing to do is
to show the headers.  In Eudora this is done by clicking on the "Blah blah
blah" button in the message.  Then you look for a line that says something
like "Received: from spam.com by diku.dk with SMTP ID 1234567 for
<xerxes@diku.dk>" with a lot of other junk in there.  This indicates with
90 % certainty that the message came from the server "spam.com" and you
should send mail to postmaster@spam.com.  DO NOT BOTHER REPLYING to the
"From" or the "Reply-To" as these are fake 99% of the time.

3. In order to prevent yourself from getting these messages in the future,
it is essential to complain to postmaster at the other site.  That way the
spammer's e-mail account will be cancelled, and you won't keep getting
messages from them.  Also, the spammer will realize you are a "problem"
because you got their account cancelled, and they're less likely to send
more mail to people like you (because they don't want their account
cancelled again).

4. Eudora can only filter items that it has downloaded.  However, it's
possible for Eudora to only download parts of a message, and then make the
decision whether to continue downloading it or not.  Since you are using
Eudora Pro 3.0, you can hold down the option key while you choose "Check
Mail" and click "Get Headers Only".  Another way is to go into
Special/Settings/Checking Mail and select "Skip messages over 2k".  That
way you will download just the headers, and Eudora will filter them.  When
it's all done, you can choose whether to trash or get each message that
comes through, by clicking on the little trash can or the fetch icon.

5. But, the best way to block mail coming from a user is to install
filtering software on the server.  That way, the message gets rejected
long before you see it, and you don't have to spend any telephone time
downloading it at all!  Talk to the administrators at your internet
provider about installing "Procmail" on your servers.
