Re: check body for spam, block sender

You can try either one:

*) Update SpamAssassin config file (/etc/mail/spamassassin/local.cf) to detect certain words/senders and increase its score.
*) Use Postfix parameter 'header_checks' and 'body_checks'. Reference: http://www.postfix.org/header_checks.5.html
