How to block "mail.spammer.com" utilizing SPAMASSA
We are finding it necessary to occassionally block email domains. How can we block an email domain "mail.spammer.com" with spamassassin working in conjunction with sendmail as the MTA? When I look at the files for spamassassin under /etc/mail/spamassassin/ I don't exactly see a file that I would add the "spammer.com" domain name to for denying spam from that address. Currently we are using the 'access' file to add email domains to be blocked but understatnd Spamassassin is a better way to go. Can someone specify how to use spamassassin to block mail.spammer.com?
