What do you think about the defers system ? Here's a part of the help file :
------------------------------------------------------------------------ --- How Fluffy Identifies Spam Fluffy does not examine the details of the sender of an email, or the subject, or where it was sent from. Fluffy is only concerned with the identity of the mail server passing the mail to it, and with the address that the mail is being sent to (which may or may not be the same as the address in the To: Cc: or Bcc: fields in the email header). Fluffy checks the mail server passing the mail over. Note that this is not the claimed source of the email, but the last link in the chain before it reaches Fluffy. As a result, forged headers won't fool Fluffy. Fluffy checks to see it the address is in the "Whitelist" of servers you want to allow to send you mail, or in the "blacklist" of servers you don't want mail from. Fluffy checks to see if the server is listed in any of the on-line databases that monitor where spammers send mail from. Fluffy checks that the email isn't being sent to a "spamtrap" address - one that only gets spam, rather than real email. If it is, not only is that mail refused, but the server sending it is blacklisted. If the mail passes all these checks, Fluffy checks to see if you have had email from this server before. If it has not sent email within a set period (24 hours, or whatever time you choose to set), Fluffy defers the email for a while. The default is 15 minutes, but you can adjust this if you prefer. Spammers don't try to send email a second time, but genuine mail senders always do. This delay also allows time for new sources of spam to be added to the DNSBL databases, avoiding the problem of new 'hit and run' spam sources set up for just a few minutes of mayhem before they are identified. ------------------------------------------------------------------------ ---- The part that I was checking is only the defers system. It looks like a quick and easy (and inexpensive) way to block some spam... ----------------------------------- Vincent Toussaint Sys.

With most good anti-spam programs, the majority of legitimate E-mail will have at least one "thing" wrong with it. Of course, there are a lot of people out there who seem to be comfortable with single criterion systems -- but they will typically block quite a bit of valid E-mail. -Scott --- Declude JunkMail: The advanced anti-spam solution for IMail mailservers since 2000.
