Strange 'undeliverable email' bounced from there

I received an email starting:
‘Hello, this is the mail server on mail0.vlnscompany.com.
‘I am sending you this message to inform you on the delivery status of a
message you previously sent.’
It was sent to my own domain email mailbox referring to an email sent to another mailbox on the same domain, but with nothing to even hint at the content being 'bounced', stating:
‘Your email was detected as spam. (Sanesecurity.Phishing.Fake.27918.UNOFFICIAL’
Norton currently rates vlnscompany.com as Caution! so I was not inclined to explore further.
It all seems dodgy.
