Thanks for your answer. The problem is users don’t even know what a mailing list is. They just select all contacts in addressbook and send the message. That’s what I want to avoid.
one way to solve this problem is to use the CHKUSER_RCPTLIMIT directive in /etc/tcprules.d/tcp.smtp. this directive limits the number of recipients a message may have; if you set this number to something low (10 should be more than sufficient, 5 is more aggressive, 2 or 3 is very harsh), then if they put their entire address book into the To: field, the server will reject the message.
more documentation is here: http://wiki.qmailtoaster.com/index.php/Tcp.smtpof course, this will immediately create a new problem, namely that your users will come screaming to you that they can no longer send email to 100 people with a single message, so i hope you have already prepared a web page which explains in simple terms how to configure and use a mailing list. in addition, before taking any action such as this which is likely to anger lots of your users, it's always a good idea to make sure that your management understands what you're doing and why you're doing it, and supports your decision.
