hi
this would probably be interesting for sys admins dealing with spam. we wrote a program to stop spammers here is the full description Nearly all of today's mail system administrators face spam as their first threat. Because of this, EnderUNIX team has written a small application to automagically monitor malicious spammer activity in your mail server logs. spamGuard is written purely to stop spammers hanging arount. For the time being, the program supports qmail MTA with multilog logging facility enabled. In the following days, it will hopefully support other mail transfer agents. Rationale: spamGuard scans your qmail log files within fixed intervals, which can be defined by yourself, say 10 minutes, and if an expression " from <[EMAIL PROTECTED]>" is matched more than a predefined value, which is of course can be cofigured by yourself, spamGuard adds the mail address to $qmaildir/control/badmailfrom file and sends qmail-send process a HUP signal. Therefore any further mails by this user will be rejected by qmail. This way, you will have a chance to detect spam before it goes any further automagically. There is also an ignore file, where you put your privileged users. Download: You can download EnderUNIX spamGuard 1.0 from http://www.enderunix.org/spamguard/spamguard-1.0.tar.gz Homepage is http://www.enderunix.org/spamguard/ best regards.
