The first question is: do you have your mail users in a > mysql database or they are in the system ? I don't quite understand your question. I would like to filter spam from/at my primary nameserver, ns1.thought.org. There aren't any real user accounts on NS1; it's just me and an "admin" account, and of course, root. Other user accounts are on inside/private hosts: tao.thought.org and ethic.thought.org. ethic is a RedHat system that I let my daughter play on. So far she hasn't gotten much spam. The spammers hit me hard. Do I need to install dspam here on tao.thought.org? (This host is my testbed so I have mysql installed here.) > > If they are in the system use dspam_2mysql to generate the table for > dpsam from the passwd file, and use dspam_genaliases to generate the > spam aliases for each user to forward the spam to. Ok, in an xterm on NS1 I just ran dspam_2mysql; nothing was output to std|[out|err]. (?) Nothing in /var/db/mysql so looks like I'm doing something wrong. dspam_genaliases prints aliases like: spam-nobody: "|'/usr/local/bin/dspam' --user 'nobody' --addspam" spam-admin: "|'/usr/local/bin/dspam' --user 'admin' --addspam" spam-www: "|'/usr/local/bin/dspam' --user 'www' --addspam" spam-kline: "|'/usr/local/bin/dspam' --user 'kline' --addspam" spam-postmaster: "|'/usr/local/bin/dspam' --user 'postmaster' --addspam" spam-abuse: "|'/usr/local/bin/dspam' --user 'abuse' --addspam" to stdout. Let's say that I want to block spam from /home/admin: the address would be admin@ns1.thought.org Where would I put the "spam-admin" alias? > > As a general note, until you're convince the hole system works ok > compile dpam with verbose_debug.

I'm beginning to get a clue, but still don't understand what I need to do re mysql. Also, what to do with the spam-aliases lines. Thanks much for your help. I think dspam will save lots of people from needness grief (and spam)! gary > -- Gary Kline kline@thought.org www.thought.org Public service Unix
