Well, spamassassin. Spamassassin identifies spam. Nothing more, nothing less. The limit of "only against incoming mail" is caused by calling spamassassin via procmail. If you use spamassassin via some other tool, it can be used against outgoing mail as well. For example, have all of your outgoing mail send to a separate smarthost that is running sendmail+mimedefang where mimedefang is invoking spamassassin. (if you run mimedefang on the same host as your web programs, I believe they bypass milters ... so that's why I say "a separate smarthost") > or any program which can limit sending spam-mail? > > Please recommend any for me.. > > my system is linux and sendmail. I'd look into mimedefang. Others might recommend the spamassassin milter, or amavis. Those are the milter options I'm aware of. There's also mailscanner. All of those will work with sendmail on linux. Though, you might also want to look into securing your web forms, and enforcing an anti-spam policy among your customers (ie. reserve the right to terminate contracts with customers who are generating spam, or allowing their mail/web configurations to exist in a compromised state).
