I may not have been clear enough in my previous post. The comment was not
aimed at this particular DNSBL, but at DNSBLs in general - especially OPEN
ones. While you and I and many others may use them for their intended
purposes, what is to keep a spammer from searching a BL - for example,
ordb.org - for open relays that can be abused? And, since anyone can set up
a DNSBL, it is entirely possible that a spammer or spam-enabler could set up
a DNSBL, go through the scanning process, then allow spammers / spamware
access to the zone to select relays to pump their spam runs through.
Personally, I don't have a problem with my SMTP server being checked out by
the DNSBLs - I keep it locked down tight, and if they find anything then I
surely want to know about it. And, I don't have any problems with the BL
mentioned in this thread. However, I don't think it is impossible that
these BLs could be used by spammers.
