Members group email being rejected when i send using my registered member email

Hello I tried for the last few days to send a group email but keep getting the following error.
We have a custom domain deerparktoastmasters.org, (club #6859), thus the members group email is members@deerparktoastmasters.org
This has been working well until the last few days and now receiving this message.  I use my registered member email to send the email and it worked well until now.Delivery has failed to these recipients or groups:This email address is being protected from spambots. You need JavaScript enabled to view it.
Your message wasn't delivered. Please try resending the message.
 The following organization rejected your message: toastmastersclubs.org.

Your DNS is missing the MX record
I see the 2 the A records but no mx record.

Please fix your MX records and try again.

Hello Brian, thanks for the help, can you direct me to instructions on where and how to do this? Is it a problem with the Host DNS configuration? We use HostPapa. I am not an IT person so do not know what an MX record is.

Our domain was setup years ago and this members@deerparktoastmasters.org group email has been working flawlessly until recently. Nobody changed any configuration or settings recently.

Hello Brian i looked it up on google gemini and it told me the following:

The email hosting platform and routing infrastructure for is FreeToastHost, the official web host for Toastmasters clubs. [ 1 , 2 ]
Recent records show that your domain uses custom domain settings to route club emails (like ) through the FreeToastHost Support Network. url=https://support.toastmastersclubs.org/kunena-2025-02-09/general-discussion/38625-members-group-email-being-rejected-when-i-send-using-my-registered-member-email]1[/url

Required MX Records for FreeToastHost
To ensure emails to your club's custom domain are not rejected or bounced, your domain registrar's DNS settings must contain the following specific MX records: url=https://support.toastmastersclubs.org/kunena-2025-02-09/support-requests/36110-club-email-not-going-through?start=6]1[/url

Please read this document for DNS settings;

This general document is as far at FTH can go as every registrar is different and you'll have to contact their tech support for specific help.

For reference, below are my club's DNS settings at GoDaddy.
