No I haven't, I'm not certain how different mail software would react.
I would want to insure legitimate mail is not affected. I set things
back to normal on the domain I was testing. I really just wanted to
see what would happen and was encouraged by the results. I'm sure
there are a number of ways to do this, but I don't know which would be
both effective and safe.
