Hi,
I guess best practice is to change your mail address. Or you mail to every postmaster you got NDR´s from (wich might be a lot of work) and tell them how to use SPF.

I did some quick looking at one time and could not find a way to identify NDR's.
Seems like there has to be a way though, I am guessing that Microsoft is blocking the NDR's from coming in and filling up bill's mailbox (lot of spam comes saying it is from him). Wonder if any of them would share how/if they handle NDR's?
One thing I did learn is you don't want to blacklist the server that sent you the NDR, that is probably a legit server and before long your email will drop to nothing since you blocked all the good servers out there!
