I hope you guys don't mind me asking here about a non Postfix issue.
I find this in the logs of our mail relay server. We are using
google's GSuite, but have a relay for some use cases...

example.com <http://example.com> is our domain, and user1 and 2 our
valid users.I cannot figure out why and how our users would be

Am I misunderstanding the log lines?
Thanks a lot!
Mohamed.
