Hello

We have been trying to send emails all day today.

But the emails keep bouncing back with the message that the domain (gmail.com) and other domains is spam and rejected it.

How can this be fixed please.

    Dear destevam_adm,

    Thanks for your reply.

    1. Please let the admin of the recipients(gmail) to add your domain in their safe sender list **** and allow list in the spam filter to see if it helps.
    2. Please make sure that your domain has SPF, DKIM, and DMARC set up properly in your DNS records.
    3. If the issue persists and you have done the suggestions above, please contact Microsoft Online tech support team which has higher permission and able to access into the back end from server. They would be able to either improve the reputation or give you a workaround (use subdomain). Please be kindly to contact your administrator and refers below steps:
    4. Go to the admin center at https://admin.microsoft.com. (This is only for administrator's account.)
    5. On the bottom right side of the page, select Help & support.
    6. Type a question or keyword into the text box. If you get a drop-down list, select the one closest to your question, or continue typing your question, then press Enter.
    7. If the results don't help, at the bottom, select Contact Support.
    8. Enter a description of your issue, confirm your contact number and email address, select your preferred contact method, and then select Contact me. The expected wait time is indicated in the Contact support pane.

    RESOLVED

    My SPF was configured with an IP4. I removed the IP entry and problem was solved.

    Seems for this problem with google, the solution is review your internal configuration.

    Thank you,

    Hello... Same issue. Added all to "safe sender", restarted, etc. And it continues.

    gmail.com suspects your message is spam and rejected it.
