Undeliverable: Inbound proxy probe - How to Block

What are these , Why are they being sent out from the Exchange server ? Why are they showing up in one users mailbox . (looks like they are being forwarded somewhere?????) i cant find it . Been trying to nail this one down for a month . I even created a transport rule but they still show up in the users mailbox.
Exchange server is version 2013 i believe with latest CU.
Can you help?

Hi anonymous user

This issue may be related to the health mailbox.

Please run a message tracking via EMS:

     get-messagetrackinglog -sender "inboundproxy@contoso.com" -messagesubject "Inbound proxy probe"

And check the recipient, which should be a certain health mailbox.

Please check if the SMTP address of the health mailbox(supposed to be "Healmailbox<guid>@domain.com") is incorrect or missing.
Add the correct SMTP address to the health mailbox and see if it will get rid of the issue.

Here is also a link in the similar situation for your reference:

Hi,

Thanks for the update!

Please have a check if the email address of the two health mailboxes match the default one(supposed to be HealthMailbox<guid>@<default accepted domain>)

 Get-Mailbox -monitoring -identity <the two health mailboxes> | fl name,EmailAddresses

If the result doesn't contain the default email address, please run the following command to add it:

 Set-mailbox -identity <the two health mailboxes> -EmailAddresses @{add="HealthMailbox<guid>@<default accpet domain>"}
