dob.sibl.support-intelligence.net

[Ian Lists]

I'm trying to figure out what is causing my server to query dob.sibl.support-intelligence.net for DNSBL look-ups.  I have only enabled spamhaus-ZEN and spamcop.net, so I'm not sure what is triggering this.  It looks like my server is having to send a lot of retransmissions, so I think it is causing SpamAssassin to timeout.

[TCP Retransmission] Standard query A papajohns.com.dob.sibl.support-intelligence.net




Thanks,
Ian
