We'll politely disagree because I am doing my best to reject mail including 
having backup servers query primary servers for valid email addresses but 
when the primary server is down, we MUST queue mail up on our servers.  If 
people choose to view that as us being the source of SPAM, then they are 
negating the entire point of having backup MX's for when stuff hits the fan.
