Hello List, we currently have 3 E-Mail Boxes running sendmail and cyrus. We serve about 50 customers and 800 e-mail adresses. The Customers usually have an Exchange-Server or directly connect to us using smtp auth. Out problem: If a customer sends out an E-mail bomb by accident or purpose, then the ip-address of our mailserver will be blacklisted! Whats the best way to avoid this? Is there a way to set some sort of limit or something? Example: If a customer with 50 E-Mail Adresses gets a LOT of spam including unknown user bounces, then i will get a lot of traffic wich will look like some e-mail attach, too. Any ideas? Thanks, Mario ---- Cyrus Home Page: http://cyrusimap.web.cmu.edu/ Cyrus Wiki/FAQ: http://cyrusimap.web.cmu.edu/twiki List Archives/Info: http://asg.web.cmu.edu/cyrus/mailing-list.html
