"postmap -q ip.add.re.ss hash:/etc/postfix/badip" tells you whether
"ip.add.re.ss" is found in the hash table "/etc/postfix/badip".
postmap.1.html has details. access.5.html explains the format of access
table lookups. For a list of IP addresses you might also want to
consider the cidr format: cidr_table(5), cidr_table.5.html.

But wait, Rich, there's more ... I am going to lead you to The Fountain
of Postfix Knowledge. When you installed your Postfix did you enter a
value for html_directory ? You should have. For Slackware
"/usr/share/postfix" would be an appropriate choice, or put that under
"/usr/local". Make a symlink from that into your apache DocumentRoot
("/var/www/htdocs" in Slackware.) Bookmark it (http://yourhost/postfix)
in your browser, refer to it often.

It gets better! Well, no, not really. But I want to tell you about the
one document which helped me start to put all the pieces together in my
mind: http://jimsun.linxnet.com/misc/postfix-anti-UCE.txt

Good luck, have fun.
