I've done some homework on this as well... There doesn't seem to be a 
(to me at least) real good satisfactory solution. Searching around in 
various places people have suggested using your MTA's filtering 
capabilities against *all* incoming e-mail to filter out NULs..... 
Since this kind of filtering is pretty expensive in terms of horsepower 
this is not an acceptable solution for me. Which so far has brought me 
back to square one, grinding my teeth and accepting the 
rejections...... Please let the list know if you come up with anything.
