I'm trying to help someone who uses Outlook for outgoing mail for their root domain, example.com, and then they set up mailgun for mg.example.com.
They made a bad judgment call and sent to an old list that hadn't been sent to in over a year, resulting in high bounces.
Now ALL the email they send from the root domain to gmail and G Suite users goes to the junk folder. They realize the bulk email send was a mistake and won't ever do it again. It's only two users using outlook for outgoing email and they now just need their ordinary email to work. They don't plan to do any more bulk sending.
They deleted mg.example.com then they submitted this Google Form to try to get the issue resolved with Google. It's been over 48 hours (the time Google indicates) yet the emails are still going to spam.
My hypothesis on why the problem isn't resolved is that they only submitted the root domain in the form to Google, not the mg.example.com. I think that perhaps they should re-create the mg.example.comand its mx records and submit the form again?
Also, they skipped one the fields in the form to submit to Google, which they said they skipped because it wasn't required. I'm not sure if that is part of the problem as well as maybe Google wants every field filled out. This is the question they skipped.
Are you able to ping any/all of the servers listed in the MX record? Please include the results of your ping tests. To ping servers listed in the MX record, use the command: 'ping gsmtp185.google.com' in all platforms. (Replace 'gsmtp185.google.com' with the results from the DNS MX lookup.)
What's the best way to resolve this problem and get their day-to-day email Inboxed as it was before the mistake they made? Thank you.
The solution, in this case, was to wait the full 48 hours after submitting the Google form before thinking the form didn't work. Google fixed the problem on schedule.
