Not sure if this is wordpress or woocommerce-specific but I've run into an issue where emails aren't being sent out if the FROM email is my personal gmail.
When the FROM header is set to [email protected], I receive emails immediately
When the FROM header is set to [email protected], I don't get any emails.

According to WP Mail Logger, emails were sent out with no errors in all instances. It's funny that the third email actually gets sent out, given that I have no control over blahblahblah.co although it does seem to be registered
Is this a gmail security thing? I do find it kind of suspicious that I'm able to enter completely random emails and claim to send emails from them, but how would I debug this issue?
