Spam got through using Rcpt to? - Any suggestions?

Post by mshanley »

wow... How in the world does this get through the filter and not even have the efa spam link at the bottom of the email
my domain is coloradoonly.com this guy is using fanshawec.ca

He sent it from himself to himself and it ended up in my email box.. how is that possible? lol

its an HTML email....
hmm.... looks like he got it to me by using X-Rcpt-To: <mshanley@coloradoonly.com> is there any ideas on how to block this kind of thing?
