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: ####@####.#### or
Return-path: ####@####.####
-> my server -> @gmail.com (or other big mail providers) -> fail
(usually with a "UnsolicitedRateLimitError" message), as both of them
have a nice SPF "-all".
Best regards from Switzerland,
Olivier
