what's a quick and dirty way to block spam
I've been running a mail server for about a year now, and just recently my users have started getting spammed from one domain. I know there are filter lists I could subscribe to and a bunch of ways I could block this garbage for good, but I need to know a quick and dirty way to just block this one address for now.
Is it as simple as putting it in /etc/hosts.deny ?
Thanks in advance,
Finegan
