Hi, using Exchange 365 and GMAIL is bouncing all emails -- unsolicited email from your IP address

I did all the domain checks and everything is checking out fine. SPF and reverse DNS are all correct.

"Remote server returned '550 5.4.300 Message expired -> 421 4.7.28 [2a01:111:f403:7052::701 15] Our system has detected an unusual;rate of unsolicited mail originating from your IP address. To;protect our users from spam, mail sent from your IP address has been;temporarily rate limited. Please visit; https://support.google.com/mail/?p=UnsolicitedRateLimitError to"

Is there a problem on the MS IP addresses right now?

    I may have jumped the gun. Last email went to 5 gmail users and either they all got it or non got it, so this morning I sent out to 5, one being my son who works with me and he got it so I concluded... but checking with another recipient they did not, so am agreeing regardless it appears DMARC and DKIM need to be set up. Last message we got from DKIM is it will be 10 min-4 days so were in the wait mode now.

    Hi BoB,

    Please take note that you have to add the cname records (they are displayed in the same popup) before it can be activated, if not you Will wait forever.

    Kind Regards,

    Benjamin.

    Sorry to keep troubling you with this. I see how to add a CNAME through GODADDY. Per your instructions and what I understand from the add CNAME process, we go to the GODADDY site and do this

    Is it what we do and then repeat for selector2? What are the consequences of hosing our domain on GODADDY if we don't do this correctly? Thanks again

    That's exactly what you have to do Bob, no consequences if you do this incorrectly.

    Please send me a screenshot when you're done

    This is the screen shot from GODADDY. The CNAME does not show up in my 365 Admin console. Would that be correct. GoDaddy did say they were saved correctly. Tks
