Thanks for your reply John!  gmail.com was just a first example, there 
are many others, and telling my users that the other servers are broken 
will not really impress them, unfortunately, and they will leave to 
gmail, outlook.com, or others.

Another live example from the current mail queue:  twitter or facebook 
notifications with:
   Return-path: [email protected]  or
   Return-path: [email protected]

-> my server -> @gmail.com  (or other big mail providers) -> fail 
(usually with a "UnsolicitedRateLimitError" message), as both of them 
have a nice SPF "-all".
