Verizon problems - what else is new

[Jeff Lasman]

Verizon has implemented something new.

My client tells me that Verizon tells them:

<snip>
Now, I don't totally understand all this, but what they're saying is 
that 
when they try to authenticate the domain that is sending the email 
(which 
should be raq41.provincetowndesign.com) the PTR record's IP Address is 
65.58.240.193...and dnssys.com reports a different IP Address (or 
something 
like that).
</snip>

I've checked our forward/reverse DNS.

The email is coming from raq41.provincetowndesign.com.  Dig gives us 
65.58.240.200.

But doing dig on 200.240.58.65.in-addr.arpa and doing nslookup on 
65.58.240.200 gives us a cname and a ptr, and only the cname appears to 
be for the exact IP#.

I'm guessing my upstream (who does reverse dns for me) is doing 
something wrong, but I can't tell what.

If you have a moment, please do some lookups and let me know what you 
think.

Thanks.

Jeff
