Assunto: Re: [exim] Defer as a spam filter
Sort of a greylisting type trick. I define my highest MX record to point
to an IP address that returns defer on everything. Many spammers hit the
highest IP address first and never return. That gets rid of a tom of bad
traffic. You can also have your highest MX point to a dead IP address.
The only difference if if you want to see a count in your logs or not.
And this trick is totally pain free.
