It is not only desirable, as Stephan already pointed out to someone 
else, it is per the spec:

"This behavior is implemented as such on purpose. From RFC5230 
(http://www.ietf.org/rfc/rfc5230.txt):

5.1.  SMTP MAIL FROM Address

    The SMTP MAIL FROM address of the message envelope SHOULD be set to
    <>.  [...]"

So what? Many people consider them spam already.

Please don't muck with things like this unless you have a really, really 
good reason...
