Good morning guys, I'm having some issues with Kallis englewood office. They use GMAIL. They are able to send emails, but they are not receiving. I checked the mailbox, it's not full, I'm not receiving a bounce back email, there are no rules, I tried to run a mail tracer but no data is showing up for today. I typed their domain at mxtoolbox, and I received this:

Have you checked g-workspace health?

Tech B 2024-11-12 13:34

If there is problem, with records/domain you should see it in dashboard when you login as root admin

Tech A 2024-11-12 13:36

Most likely domain records/expired domain

Any ideas? @all 👀

Tech C 2024-11-12 14:17

check the email headers

Tech C 2024-11-12 14:18

nvm, so posgrp.com is the sender?

Tech A 2024-11-12 14:18

yep

Tech C 2024-11-12 14:19

who is the recipient?

Tech A 2024-11-12 14:20

wait, so posgrp.com is the one that's not receiving,sorry. I sent an email from their email account to my account, I received it. I replied, and they didn't got my email

Tech A 2024-11-12 14:20

They are not receiving emails since yesterday

Tech D 2024-11-12 14:20

forwarding rule maybe? have you check if they have any forwarding rule?

Tech A 2024-11-12 14:21

No rules

Tech C 2024-11-12 14:21

mx record is missing on the dns

Tech C 2024-11-12 14:22

Starting in April 2023, we made it possible to use one MX record to set up Gmail. This change has no impact on mail delivery or reliability. Important: We recommend using these instructions if you’re setting up new MX records or if you need to change your MX records. If your current configuration is working, don't change your MX records. The Legacy version (5 MX records) will continue to work indefinitely. Name/Host/Alias* Priority Value/Answer/Destination Blank or @ 1 SMTP.GOOGLE.COM * Domain hosts use different labels for the name and value fields. Some hosts also require a period at the end of smtp.google.com.

Tech C 2024-11-12 14:23

so, on the dns create a mx record pointing to smtp.google.com

# Fix Gmail not receiving emails due to missing MX records

## Problem

A client office using Gmail could send emails but was not receiving any incoming messages since the previous day. The mailbox was not full, no bounce-back emails were generated, and no email rules were configured. Mail tracer showed no data for the current day. DNS lookup tools revealed missing MX records for the domain (posgrp.com), with Google Admin Toolbox showing "Check was not possible" and MXToolbox reporting "DNS Record not found" errors.

## Resolution

1. Verify the issue by checking the domain's MX records using Google Admin Toolbox or MXToolbox
2. Access the domain's DNS management console (typically through the domain registrar or hosting provider)
3. Create a new MX record with the following configuration:
   - Name/Host/Alias: Blank or @
   - Priority: 1
   - Value/Answer/Destination: SMTP.GOOGLE.COM
4. Save the DNS changes and allow time for propagation (typically 15 minutes to 24 hours)
5. Verify the fix using Google's Check MX tool to confirm the MX record is properly configured

Note: Some DNS hosts require a period at the end of smtp.google.com and use different labels for the name and value fields.
