Slamp, that's not how dnlsbl's work
DNS Blacklists work by using txt entries.
For example, this ip address attempted to send me mail, but was banned
by spamhaus.
70.103.74.235
So you put the order of the octets in reverse and put the dnsbl
suffix. Then you look for the txt record:
$ host -t txt 235.74.103.70.sbl-xbl.spamhaus.org
235.74.103.70.sbl-xbl.spamhaus.org text
"http://www.spamhaus.org/SBL/sbl.lasso?query=SBL47341";
One of Google's mail servers is 66.249.93.114, so I do the same to google:
$ host -t txt 114.93.249.66.sbl-xbl.spamhaus.org
Host 114.93.249.66.sbl-xbl.spamhaus.org not found: 3(NXDOMAIN)
The Google one is not listed in spamhaus, so I get an NXDOMAIN.
"ping" doesn't come to the equation with DNSBL.
Thanks,
Erik

think these are part of the qmailtoaster-plus, so it might be a good
idea to take them out.
