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?

    plus 1 for Benjamin's very helpful post on page 3 of this thread.

    This fixes it.

    A little convoluted if you are not an e-mail admin, but follow the steps he lays out & it works.

    follow his link to https://www.alitajran.com/configure-dkim-record-for-office-365/

    As a prior step, I added the the TXT records mentioned under https://www.gmail.com/postmaster/

    This DID NOT fix the gmail bulk BCC issue, but I've left them in.

    Thank you Benjamin !
