Sorry... I forgot to change my setting to Plain Text in my previous
post.... we do all make mistakes sometime.
That message will be in one of my spamboxes.
I am trying to "spam proof" (not that this is really possible, but I
want to do the best I can) a new server I am building for web and
mail hosting.
Is it better to use the global procmailrc file for achieve this?
Is there a list of "bad" domains and dsn available? Can anyone point
me to a reliable recipie to help in this task?
Don't reïnvent the wheel. If your server is powerful enough, install
SpamAssassin.
For a serious mail server, in order:
1. SMTP-level: DNSBL, DCC-check, etc.
2. central: virus detection
3a. user: sender whitelist
3b. central: spam detection
4. user: procmail
(please comment)
Central spam-detection will not likely use bayesian or other techniques
that work with user dependent information. Configure SpamAssassin for
central usage.
Give the user the choice at which Spam-Score-range the mail is delivered
in his spambox, for example:
10 or higher : discard
5 or higher : to spambox
else : accept
Run a daily cron-job that deletes old (like >1 month) messages from the
spamboxes of all users.
