plus.net mail account rejecting messages as spam from Office 365

Starting yesterday morning, Plus.net is rejecting messages (mainly from Office 365) sent to my hosted domain email address.  If I send it to my native Plus.net email address (dave@ [Removed].plus.com) the message gets through.  Has something changed or do I need to change something on my DNS records for the hosted domain.  I have added the domains to my white list in the email set up and I have reduced my spam filtering strength but this has had no effect.

Here is the error message the sender receives.

Thanks

More Info for Email Admins

Status code: 550 5.7.350

When Office 365 tried to send the message to the recipient (outside Office 365), the recipient's email server (or email filtering service) suspected the sender's message is spam.

If the sender can't fix the problem by modifying their message, contact the recipient's email admin and ask them to add your domain name, or the sender's email address, to their list of allowed senders.

Although the sender may be able to alter the message contents to fix this issue, it's likely that only the recipient's email admin can fix this problem. Unfortunately, Office 365 Support is unlikely to be able to help fix these kinds of externally reported errors.

Thanks for getting back to us @dave29, I appreciate it.

 

I would need to send this over to the relevant team to investigate but I would need the full headers to do so.

 

Please can you PM me with this and I will pick this up for you.
