My CIDR anti-spam doesn't seem to be working

I have a file named spam.cidr with CIDR notated addresses
like this:


219.110.200.0/24 REJECT "550 SPAMMER NINCOMPOOP REJECTED!!!"
220.108.0.0/16 REJECT "550 SPAMMER NINCOMPOOP REJECTED!!!"
220.144/16 REJECT "550 SPAMMER NINCOMPOOP REJECTED!!!"
221.252.145.72/29 REJECT "550 SPAMMER NINCOMPOOP REJECTED!!!"
222.0/12 REJECT "550 SPAMMER NINCOMPOOP REJECTED!!!"


I do a postmap of this file and it creates the .db file.
Now, I just received a spam email from:

Received: from buss.com (FLH1Aat125.fks.mesh.ad.jp [220.144.140.125])
********by mydomain.com (Postfix) with ESMTP id 3B39975E590


Can anyone please tell me why this IP address was not blocked,
even though I have a 220.144/16 entry in my spam.cidr file
listed above?

-Thanks

In your main.cf file, under "smtpd_client_restrictions",
do you have "check_client_access cidr:/etc/postfix/spam.cidr ?

Also, according to "man 5 cidr_table", it should be 220.144.0.0/16 and
not 220.144/16

P.S. Fred, you can test your cidr file to see if it matches, with:


postmap -q 220.144.140.125 cidr:/etc/postfix/spam.cidr

Thanks, that did the trick. I posted a message some time ago
about checking the syntax of the CIDR entries, and was essentially
postfix doesn't support it.
