I had trouble that for one of my addresses forwarding to my gmail account systematically all of them got sent to spam, even if it's literally a reply to a message that I sent from gmail and repeatedly set "not spam" at it. In the end the only thing that worked was to add an explicit filtering rule saying "never send to spam" for that address.
