email function not working -- not isolated

Agreeing with another post, just so you know the problem isn't isolated. Cannot email to all members or to officers. 
I tried earlier on Sunday and received this error message:The original message was received at Sun, 14 Dec 2025 22:33:43 GMT

I attempted again after the update. I didn't get an error message, but no one received the emails. Thanks for your attention to this.
