MSN throttling any mail sent from METROCAST accounts

Please assist asap!!

For weeks I have not been able to receive any messages from metrocast.net emailers.  Same with others with .msn emails.  No error messages are usually received by the sender.  The below was received today and I spoke with a metrocast technician who explained that this is an ongoing issue that emanated from an event many weeks ago that had been resolved...  Please advise!!

Thank you!

Answer

"The mail server IP connecting to Outlook.com server has exceeded the rate limit allowed. Reason for rate limitation is related to IP/domain reputation." If you are not an email/network admin please contact your Email/Internet Service Provider for help.

As you can see from the error message you need to be persistent with Metrocast.  You would not be "throttled" or blocked now if the issue was not still ongoing.  They need to contact Microsoft at *** Email address is removed for privacy ***.  You cannot mitigate this yourself.
