Club Email Addresses Distribution lists are not working

First noticed 7 days ago and again yesterday. Deerwood Toastmasters #902585 emails sent to "Officers" and "Members" distribution lists are not working. When I send an email to either list, the email shows as "Sent" in my sent box, but no one receives them, including myself as the Secretary. We've never had any issues before.

I use Outlook 365 and Google Chrome.
Thank you for the help!

It appears some officers/members on the list receive the emails, but Secretary does not seem to be working from the
email listed for Secretary aaron.fontinel@fontinel.com

I can see the emails being processed. Some email systems do not like email from and to the same email address, check your spam box.

Thank you! I started receiving the Secretary copy of yesterday's emails...today, about 20 hours later. It appears things are working now.

I appreciate you looking into our issue.

All the best,
Aaron
