Re: check_badrcptto, to prevent backscatter

  Tim's view seems appropriate. His script is centered on qmail, and 
mine is centered on postfix (or more specifically, on /etc/aliases). 
Both scripts are probably best in their current form with appropriate 
disclosures. Let me know if there is any prep work you would like me to 
do to my script.
