[SURBL-Discuss] SURBLs in main domain DNS

hi all, new to the list :D

I have a question. Im running SA and using the SURBLs as part of it on a domain serving 100,000+ daily. Ive decided to take the local DNS cache of the SURBL files and had a look at the documentation for dnsrbld etc. Now I just had a word with one of the network guys who suggested that instead of me re-inventing the wheel by using our domain dns to point to a local rbldnsd machine hosting the SURBL files that i simply just put them onto the man DNS.

I presume there is nothing wrong with that, or would there be any strange consequences. Is there anything else i should know before I go ahead?

thanks all
