Setting to disable "Email Spoofing" indicator

Hi,

I'm using an email alias service, and i'm often seeing a "Potential spoofing attempt detected in address header" bar + exclamation mark in the sender name.

I assume this is because the email is send from the alias service, and not the original sender.

Please provider a setting to disable the spoofing indicator - it's clearly not wanted in these situation, and many people use these services nowadays.

Thank you!
