In my >5 years experience running a mail server through which gmail users send authenticated mail, that is not accurate. To confirm that nothing has changed, I just looked at the mail logs, and in the last 24 hours I don't see a single instance of gmail doing what is described. In every single case, the envelope sender address is user@mydomain, not user@gmail.com.
- vacri 12y agoAre the users' gmail accounts 'gmail.com' or 'mydomain'? Because I've sent mail from servers using a google mailbox to authenticate, and the from field was overwritten with the name of the mailbox used.
- agwa 12y agoThe users' gmail accounts are at user@gmail.com, but they're sending mail as user@mydomain, via mydomain's authenticated SMTP server. This is exactly the scenario described in the comment at jwz.org.
- vacri 12y agoI read it as the opposite of jwz. You say your users are sending mail via "mydomain" SMTP. jwz says his users are sending mail "from their phone up to Google's SMTP server". The goog then sends mail to the receiver at 'dnalounge' MX, where it's then shuffled back to the receiver's gmail mailbox. I don't read his setup as having the sender involved with the dnalounge SMTP server at all.
