"Gmail couldn't verify domain sent message.."

Hi All,

I’m getting this error in Gmail ever since the last update. “Gmail couldn’t verify that mydomain.com actually sent this message (and not a spammer)”

I’m still getting emails fine, but now we receive this message every time a new form fill comes in. I’m getting no errors from Contact Form 7 on the backend, just only when receiving the email in Gmail.

Any thoughts on how to fix this?

Thanks!
