They need a rapid clue injection. RFC2821 is the new SMTP spec.,
published last week. It says:
"There are several types of notification messages which are required
by existing and proposed standards to be sent with a null reverse
path ..."
If you don't use an empty envelope sender you risk creating a mail
loop.
