Blocked using DNSBL

[AnhKhoi]

I have enabled the DNSBL feature (bl.spamcop.net, psbl.surriel.com, bl.spamcop.net, noptr.spamrats.com, spamrbk.imp.ch, db.wpbl.info, zen.spamhaus.org) the way this is 6 months. But PMG today I do not know why some external emails sent to pmg are rejected.
Error:
Postfix / postscreen pmg [31141]: NOQUEUE: reject: RCPT from [209.85.167.48]: 46605: 550 5.7.1 Service unavailable; client [209.85.167.48] blocked using psbl.surriel.com; from = <name@gmail.com>, to = <name@local.domain.>, proto = ESMTP, helo = <mail-lf1-f48.google.com>

Help me, please.

Thanks all.

well, it looks like the IP from which the email was being received, was blacklisted by a few lists (SORBS).
e.g. check:
- MXSuperTool
- multirbl.valli.org
