Secure Emails being blocked

Hello,
I should have received an email from my insurance provider but your system is blocking it. They have received a bounce back email which states you have marked it as spam. I am apparently not the first plusnet customer to have experienced this either. Please can you add their details to your 'legitimate' list so they can send me my documentation please? How do we go about fixing it?
This is the bounce back detail:
'Recipient email server: mx.avasin.plus.net[212.159.8.200] Rejected because: 552 Spam Message Rejected'
These are their IP's - Their sending SMTP servers are 18.130.67.165 and 18.130.3.176
Thanks,
Charlotte

It might be that the IP addresses are coming from Amazon AWS servers without proper authentication. both the ip's listed trace back to AWS Compute servers.
They might not be on a "Blacklist" of spam addresses per se, but some places (like Plus net admins!) tend to block places like AWS without a valid way to authenticate the sender. (It stops a heck of a lot of spam emails!).

Hi Bill,
Thanks for your thoughts. I know the secure email provider hosts in AWS which would explain why, just frustrating as I can't receive my documentation over email if this can't be resolved.
Traditional post is too slow for my liking!

Hi Charlotte,
A warm welcome to the forums.
It would help a great deal if you were able to access the full mail headers of the bounce message being sent back to your correspondent.
Plusnet use the pan-industry Cloud Mark platform for managing spam. I would suspect that others receiving mail from that sender have flagged it as spam and thus it has acquired a poor reputation.
@JW is this on support's radar please?
