Hi,

Anyone else seeing this on their maillogs?

Apr  8 19:51:31 xxxxx postfix/smtpd[87109]: NOQUEUE: reject: CONNECT from mx2.freebsd.org[216.136.204.119]: 554 Service unavailable; Client host [216.136.204.119] blocked using dnsbl.sorbs.net; Open Relay See: http://www.dnsbl.sorbs.net/cgi-bin/lookup?IP=216.136.204.119; proto=SMTP

Querying the sorbs.net database reveals:
