If I remember correctly this isn't the first time this issue has cropped 
up.  I'm fairly certain that it's even been discussed on this list 
before.  Anyway, I've had the following bit of code in my .tmda/config 
for years:

# This is where bounced email will go.
# You probably want a line in your incoming filter
# that matches this email and has a drop action
BOUNCE_ENV_SENDER = "[email protected]"

I also (at one time) ensured that the skeleton setups used by TMDA-CGI 
included this same code as well as the appropriate drop rule in the 
incoming filter.

It certainly isn't a new situation where MTAs are refusing emails with 
null envelope senders.  It's been a frequently exercised rule for 
reducing the amount of spam that gets into the mail system since 
spammers often used to leave the envelope sender empty in the effort to 
get into your inbox.
