Todd, thanks for the insight.
Jason,
Many ISPs refuse (for one reason or another) to delegate RDNS.
Instead of delegating the RDNS to you, would they make the changes for you?
Say, give them a list of your IPs and what you would like the RDNS to be?
I guess I'm very fortunate to have worked
Agreed. However, this is happening to us. (a la AOL policies and others to
follow) and we have to adapt.
As I pointed out, I think the value of RDNS (regardless of it not stopping
or slowing down spam) is that it identifies the operator of an IP address
more clearly than the large netblock
For those wondering what we are talking about:
http://www.faqs.org/rfcs/rfc1912.html
RFC 1912 - Common DNS Operational and Configuration Errors
Please consider RFC1912 section 2.1 that doesn't *require* that the reverse
DNS entries, but makes it clear that not having one is a use at your own
I wanted to throw this question to the list:
1) Who does *NOT* have Reverse DNS (PTR) entries for their mailservers?
2) If so, why not?
Personally I think reverse DNS entries adds an ounce of ownership to who actually uses
an IP address. For instance, I have several IPs given to me by my colo
WEIGHT10weight x x 10 0
WEIGHT20weight x x 20 0
WEIGHT30weight x x 30 0
WEIGHT40weight x x 40 0
WEIGHT50weight x x 50 0
Would
