[Asterisk-Users] ATTN: Keith

[Huddleston, Robert]

As an isp I can tell you that we run into this problem on a daily basis. We
see three troubles:
A) No reverse (PTR) record at all
B) Reverse (PTR) but no forward to match
Which a) and b) usually cause the most troubles and...
C) A+B but with a domain of the mail server trying to send mail.

Regardless the previous poster said they couldn't send on some cable company
residential -- well that was in the TOS when you signed up and thus you
should be faulted for that.

We are willing to oblige any of our customers with reverse DNS entries
(PTR)... 
But that was way OT so sorry all.. Just my 0.02

according to RFC's your required to have reverse lookups on ur mail server,
so blocking based on this is perfectly legitimate.
