Sender or Returh-Path, whatever..

Shouldn't be your provider's mail server to set it? Both of my SSL-enabled 
mail servers, that are authenticated (GMail and the Italian postal service) 
set this correctly, thus I don't have the SPF_NEUTRAL error on them.

If you "forge" the Return-Path, by simply not providing any protection about 
its value on the mailserver, nor on the client, then I'd say that the 
SpamAssassin behaviour is perfectly fine.
