I know all about RBLs... how can any RBL, based on the information
presented by ARIN about 70.97.153.82, decide that it is part of a
cable/dsl/dialup? Is there another record in ARIN that I'm missing, one
that declares, ``I'm a dialup pool?'' Of course at this point we're back
to the policies of an RBL maintainer.
But in this case we aren't talking about RBL maintainers, we're talking
about Godaddy. I was attempting to provide some questions to the OP
which he could use to figure out how this situation happens, how his IP
got there, which he could then use to formulate some kind of a response
to Godaddy. Does ELI possibly publish its own list that indicates the
IPs are cable/dsl/dialup? If so, then this is something that the OP
should take up with ELI.
Sometimes ISPs report to RBLs which blocks are used for their clients,
sometimes the RBL maintainers just figure it out for themselves, or
perhaps they ask the ISP. Other times I'm sure they make a good guess
and then get complaints from the ISP. There's no official record of
this stuff that I know of, but it works pretty well. AOL should not
be accepting mail from your server if your server might be your Mom's
worm-infested PC.
Of course some day worms will be smart enough to lookup the MX for the
domain if their host and ask it to relay for them. That will be a fun
day - every ISP in the world will have to implement authenticated SMTP
in the same month. There will probably be a public outcry. Fun, fun.
