However, IMHO, it is better to deny access to spammers/abusers right at the MTA port (25) For sendmail, etc/mail/access can contain things like: cyberspammer.com 550 We don't accept mail from cyberspammer.com 59.117 550 We don't accept mail from spamming IPs 64.2 550 We don't accept mail from spammers com.br 550 We don't accept mail from Brazil com.ar 550 We don't accept mail from Argentina com.cn 550 China GO AWAY *.info 550 Keep your INFO to yourself! After changing /etc/mail/access; do a make;make install as root in /etc/mail/ this will create a new /etc/mail/access.db file, which sendmail will read during the smtp connect phase of the transaction, so spammy gets Rejected before any spam gets into your box, and BEFORE it has to be transported and analysed by spamassassin. Faster, more effecient, less load on your server and bandwidth, and the spam stays on spammys server undelerivable!
