Was wondering what the deal is with blackhole.isi.edu, seems that it is
authoritative for RFC1918 addresses (private service). I am running
sendmail behind a firewall w/NAT so all my machines behind the firewall
are of the 10.0.0.xx address.
When sendmail tries to do a reverse lookup of these addresses, the query
usually times out, or takes a long time. Is the problem with
blackhole.isi.edu. Seems if you do a reverse lookup of a 10.0.0.xx
address on blackhole.isi.edu, it times out a lot or is very slow.
Thanks
