Out of curiosity, which list has you listed? Some will block whole ranges
that they believe to be Dynamic (DSL/Cable/dial-up) just from their name
returned from the PTR lookup.....Although mine is static it returns:


Asking dns2.knology.net. for 118.172.214.24.in-addr.arpa PTR record:
Reports user-24-214-172-118.knology.net. [from 24.214.63.67]

Answer:
24.214.172.118 PTR record: user-24-214-172-118.knology.net. [TTL 600s]
[A=24.214.172.118]IF you run this IP through the spam database lookup you
will see that at least one (Five-Ten) has it blocked as being a part of a
range that they block.YOu should get with your provider and make sure your
IP is not part of a Dynamically assigned block at all and doesn't return a
name that might indicate it isEric S
