You see the error "spf_validate_mailfrom: No valid from; using sending address: postmaster@" show up in your Messaging Gateway scanner logs
Last Updated April 28, 2016
When revieing your SMG scanner logs, you see many instances of the following error:
spf_validate_mailfrom: No valid from; using sending address: postmaster@
This happens when SenderID is enabled and an email is received with a null sender ( mail from: <> )
This entry is erroneously logged as an ERROR, but that is not accurate. This is simply an INFO level notification that can safely be ignored. This will be addressed in a future build so the entry is logged approriately.
