I'm automatically forwarding all my emails from my secondary Gmail account to my main one, using the feature in the "Forwarding and POP/IMAP" setting page.
My secondary account received a few emails in the spam folder and those emails didn't get forwarded to my main account. I marked them as non-spam, but they didn't get forwarded either.
Is it possible to forward those emails "seamlessly" like it happens for the emails forwarded automatically?
If I try to forward them manually, the forwarding creates a new mail in the thread.
