Emails from a friend are being saved in my Spam folder despite setting all spam emails to be labelled as such and sent to my inbox. My friend is sending the email BCC . The authorisation info is as follows Authentication-Results: ukmail.iss.as9143.net; spf=pass (220.127.116.11;gmail.com); dkim=pass header.d=gmail.com; dmarc=pass header.from=gmail.com (p=none sp=quarantine dis=pass)
If I give thums (not spam) up to email in spam folder the email moves to inbox and then sometime later moves back to the Spam folder
NBX-Spam-Action only appears if message is moved to another folder.
With the absence of the X-Spam headers it is likely an email client is performing the spam filtering. To confirm this consider creating the following filer rule in webmail: If an email appears in the Spam folder with its flag set to grey then it was: (a) not identified as spam by Virgin Media; (b) moved from the Inbox to the Spam folder by another (non-Virgin Media) process.
