Blacklist (ISPmanager)
From ISPWiki
A Blacklist is a list of e-mail addresses, IP-addresses or mail domain names that are originating with known spammers. You can use blacklists to filter out unwanted e-mails, as most e-mail applications today have filtering capabilities. The Blacklist is a useful solution in case dnsbl or greylisting cannot block numerous emails that pass through your server.
The blacklist feature is only available for administrators.
You can provide an e-mail addresses, IP-addresses or mail domain name to be blacklisted.
- Email address is provided as "spamer@spam.dom". If you are running Exim, you can provide a mask "*spamer*@spam.dom", where "*" is a random symbol.
- Email domain is provided as "spam.dom", if you are running Sendmail or Postfix. If you are running Exim, provide a mask "*@spam.dom".
- IP address is provided as "12.34.56.78".
You can choose what you would like to do with rejected senders: reject either with a standard message or with specified message. This allows you to decrease mail server load caused by a large amount of spam.
