Hello, I cannot receive verification mail from dangdang.com. mail.log shows below:

Oct 17 22:50:50 mail postfix/postscreen[14076]: CONNECT from [221.122.85.31]:26559 to [xx.xx.xx.xx]:25
Oct 17 22:50:50 mail postfix/dnsblog[14077]: addr 221.122.85.31 listed by domain b.barracudacentral.org as 127.0.0.2
Oct 17 22:50:56 mail postfix/postscreen[14076]: DNSBL rank 2 for [221.122.85.31]:26559
Oct 17 22:50:56 mail postfix/postscreen[14076]: DISCONNECT [221.122.85.31]:26559

What's wrong and how to fix it?

It's blocked by the DNSBL vendor "b.barracudacentral.org" you use.
You can whitelist it in /etc/postfix/postscreen_access.cidr.
