This was my bad when I sent this.  I should have been more specific with the 
exact ranges that we are sending from:

148.105.11.0/25
148.105.12.0/24
148.105.13.0/24
148.105.14.0/25

The ranges listed above have rDNS and and actively sending.  Since allocation 
of IPs for sending is rather dynamic on our part, the rDNS piece isn’t 
something that is setup until time to send.

Oh, OK. You might tell UltraDNS to return NXDOMAIN rather than SERVFAIL for the rest of it.


My goal in the email was to hopefully fix any classification receivers might 
have set from the previous owner of the range. Was hoping that including the 
entire range would be easier for anyone that might have the range blocked or 
classified accordingly.

Thanks for the feedback.
