As you know, Google will suggest a translation for incoming emails.
I don't want to google translate my sent emails from an automatic language to another, I want to tell google that this email wrote in Persian language !
how can I do that?
I already tried
<html lang="fa"> and
<meta http-equiv="content-language" content="fa"> and custom header
Content-Language: fa-IR but still no effect in Gmail !
By the way, Is there any way to turn off this suggestion at all ?
