Spam

Finally I have built it and deployed it. Apparantly, it DOES NOT WORK(detects spams correctly, but did not take any actions!), but I hope the virus filter will be working, as the viruses are growing too fast.

Dong CHE has told me that mail from mail.freebsdchina.org has been bounced back because it was listed in rblplus.mail-abuse.org. From the query page I found mail.freebsdchina.org were listed in mail-abuse.org’s DUL by mistake (I believe so because the mail.freebsdchina.org block is not owned by dial up user).

With more and more aaazzz’s received on beastie.frontfree.net, it makes me to seriously consider the possiblity to set up a set of early filter on postfix.

There are two common way to process unaccepted letters: One is bounce, a.k.a. give the sender a message saying “Your letter is bounced.” Another is discard, in other words, drop the letter silently.
