Thanks Erik and Eric. I added the link in
http://wiki.qmailtoaster.com/index.php/RBLs.
I did a test according to Erik and he is correct, ping is not part of
the DNSBL equation. Thanks again!
Just for my curiosity's sake.
# ping sbl-xbl.spamhaus.org
ping: unknown host sbl-xbl.spamhaus.org
# host -t txt 118.13.108.202.sbl-xbl.spamhaus.org
118.13.108.202.sbl-xbl.spamhaus.org text
"http://www.spamhaus.org/SBL/sbl.lasso?query=SBL47393";
118.13.108.202.sbl-xbl.spamhaus.org text
