I've just reproduced the described behavior via a test message from Gmail.
On the other hand, I've also just reproduced it via test messages from every other one of my email accounts, across multiple providers as well as the various instances I run for my own use. The only one that didn't repro was Office 365.

- yipeedipee 7y agoWe use a mail flow rule to remove the header when it goes through o365 outgoing.
