I will not use blacklists on any machines -- there are too many false  
positives.

 From my experiences, the people who both run the blacklists, and  
those who report them are all far too fanatical to be trusted.

I've had servers reject email from large ISPs and companies, because  
they were somehow in a list.
I've often found my own servers -- dedicated and shared -- somehow in  
a list because another machine at the same facility had php  
compromised to send spam.
I had to leave a host once, because an RBL didn't care that my  
machine was unaffected - too many machines at the facility i used had  
been compromised, so they blacklisted several gigantic ranges.

If you're fine with that -- great.  Using some simple spam filtering,  
along with SPF to minimize job jobs, I dont see too much spam in my  
inbox.  More importantly, I'm able to receive all the mail i need.
