Giving up on 66.80.68.86.
So 66.80.68.86 is hosting.midvalleyhosting.com. It is also the address
of mail.midvalleyhosting.com which is the MX record for
computer-go.org. So I think we know where the block is.
Looks like such an obnoxious spam filter!
For what I believe are legal reasons, blackholes.us does not list
spammers, but merely documents which IP addresses are allocated to which
countries and to which ISPs. There is a strong correlation between the
countries and ISPs they track and the countries and ISPs reputed to be
the sending source of spam.
