I have a question about PTR records: can anyone confirm or deny that 
some ISP's are refusing mail from any domain without a PTR?

I know that it's routine to require a PTR record from a sending host: 
that's not the issue. What I think is happening, however, is that emails 
from "bill at xyz.com" won't be accepted unless there is a PTR record /for/ 
"xyz.com", not just a one-size-fits-all PTR for the "real" address of 
"xyz.com". In other words, if I use "bill.com" as the mailhost for 
"xyz.com", "wxy.us", "abc.org", and some other domains, will I need to 
have a PTR record in place for each of those domains?

TIA.

Bill
