At the moment we've running hourly a scheduled vb-script that filters out any error lines of the imail logfile and send it via email to the postmaster
For example: ====================================== FROM TO [EMAIL PROTECTED] [EMAIL PROTECTED] [EMAIL PROTECTED] [EMAIL PROTECTED] [EMAIL PROTECTED] [EMAIL PROTECTED] [EMAIL PROTECTED] [EMAIL PROTECTED] ====================================== So we can see which of our customers has forgot to activate the SMTP-Authentication (if outgoing), or which delivery attempts failed (if incomming). But back to the idea of blocking incomming smtp-connections of known spammer-IP's: Wouldn't it be great if someone writes a small tool with the following function: 1.) gathers all Sender-IP's from the declude logfile with a certain weight. (for example 200% of the hold value) 2.) maintains a list of this IP-Adresses and removes them after a certain time that no new spam with the same IP was catched 3.) creates a IP-blocklist for Imail so that it can block any furter smtp-connection attempt from this spamming IP's Markus > -----Original Message----- > From: [EMAIL PROTECTED] > [mailto:[EMAIL PROTECTED] On Behalf Of Rifat Levis > Sent: Monday, June 16, 2003 2:52 PM > To: [EMAIL PROTECTED] > Subject: Re: [Declude.JunkMail] DSN:Tarpitting and declude > firewall integration integration > > > Hi Bill , > > I wrote a small VB program . > ---------------------------------- > Here is more details about the system. > > I am using the KIWI syslog server software to send the logs > to the SQL You can specify in IMAIL syslogs server ip > address .(IF you run KIWI on the same machine ,you have to > stop IMAIL syslog ) > > I have wrote a small Visual Basic Program which scan the SQL > database for " ERR ....
