Re: example.com/net/org DNS records
Roger Marquis [1/5/2004 3:19 AM] :
What spam did you see that forged example.* in the sender envelope / rDNS?This is the best explanation I've read so far. Problem is, it's not a compelling rational. Is this really the only reason for assigning NS and A records, violating the RFC, and breaking thousands of spam filters in the process?
example.* is well worth special-casing, I dare say, if you find spam being sent with it in the headers.
