Is this an abuse problem? some ISPs require their domain to be in the rdns in an effort to herd abuse reports to the correct org. Is this generally considered useless? Is it generally considered OK to hand relatively untrusted users the keys to their own rdns? (I'm forcing my own customers to have a rdns of something.xen.prgmr.com for several months, Much to the chagrin of many presumably innocent and legitimate customers. )
We allow RDNS controls to RapidXen customers since January 2009. It seems to be ok. We do have the ability to disable RDNS access to specific users if we feel it is being abused, however. -- William Pitcock SystemInPlace - Simple Hosting Solutions 1-866-519-6149
