Folks,

I uploaded WCGL100B.ZIP on the BBS.   This is the BETA version 
of the anti-spam Wildcat! Grey Listing system.   I posted for 
early explorers and testers.

GREY LISTING is a very highly effective ANTI-SPAM system.  It 
works on the basis of REJECTING the incoming mail and using the 
idea that all GOOD MAIL will retry again where it is then accepted.  
Since most BAD MAIL will not try again, you will be able to see a 
very high blockage rate.

Summary of how it works:

     Mail Comes In

     SMTPFILTER-WCGREYLIST checks the greylist to see
     if you want to test it.  The greylist if your address
     or the addresses you want to protect.

     If the mail is for an  address in the greylist,   the mail is 
     rejected with a 451  code.  

    451 tells the sender 

            "Temporary Rejection. Try Again"

     If this was a real GOOD system, following all the
     rules of retrying, then it will reschedule to try again
     with 1 to 60 minutes, typically.   When the good system
     tries again with the PERIOD you set in the setup, then
     the mail is accepted the second time around.

     GREYLISTING works because the BAD GUY doesn't care. He
     doesn't listen and doesn't try again most of the time.    
     He might try again with a DIFFERENT message, but not
     the same one.

It is a controversial method.  No one likes to see mail be rejected 
the first time, especially for BUSINESS systems.  But if you are
running a real SMTP server, then typically there do not no problems.

So the system comes with WHITE LISTING, AUTO-CHECKING FOR WHITE 
LIST, features to avoid using greylisting on your social or 
business network.

The system works so well, if I got 3 spams in the pass three weeks, 
it is alot!!

It also comes with web-base manager to help you manage it, and 
also see the statistics.

NOTE: At this time, you have to run the statistics in order to 
PRUNE out old blockages of mail.   For now, you should do this 
once and awhile.  At some point, we will have a WCEVENT idea.

Check it out!!  I've been running it non-stop for the last 4-5 months.

All ideas are welcome especially for the web-based AVS manager.
