Can't send to gmail

[BigBoy7]

I have a Galaxy A40.  I'm running the standard Samsung email app - have done for years.

A little while ago, it stopped delivering mail to all "gmail" addresses - returning an error message.

I just unintalled and reinstalled the email app. It then sent just one message to a Gmail address, but no more after that.

Ideas, anyone?

Same here. Started a few months ago on my S9. All emails sent to Gmail bounce back with this error:

Messages missing a valid messageId header are not 550 5.7.1 accepted.

Hi there

I have had the same issue recently. My Samsung A50 and Samsung Tablet will no longer send messages to Gmail accounts. Both are using the native Samsung mail app. However I can send message from my PC using outlook no problem.

Did you ever get a resolution to the issue?

Has this been figured out yet?

I have tried work around and even had my ISP make some changes on the server and it still has not helped.

HIi  No, I still don't have a solution.  I have switched to Gmail, which I don't like using at all.
