Re: Using a spam-trap e-mail address with greylist

I see your principal, but dont think it will go very far in reducing  
spam.  Blacklists dont work very well with spammers.  Sad fact is most  
spam is coming from zombie boxes whose owners dont know they are being  
used for spamming.  So your blacklist wouldnt block very much spam.  A  
spam filter like bogofilter or spamassassin that you 'train' by giving  
it spam and nonspam messages works much better.  However, even those  
dont do a perfect job in blocking spam.  I run bogofilter, and Im  
catching around 20000 emails a day with a better than 95% success  
rate.  Sometimes a message is put in the filter that isnt spam.  If  
that happens and the user lets me know, I'll pull it out and feed it  
to bogofilter as good email.  Im currently setting up a new mail  
server (due mostly to the huge amount of email I process) and am  
looking at implementing greylist in addition to bogofilter.
