Disable proxy for the mx records…

Name Server: keaton.ns.cloudflare.com
Name Server: susan.ns.cloudflare.com

How can i do?

I think it’s already non proxy

I would suggest to check your exim4 mainlog.

Look in too last two logs

I also notice this i not added this, it add by self

I research about all this ip address
This all IP owned by ripe.net

Honestly, I do not start reading logs from pictures, either use screenshot or copy&paste the logs.

That are bots that do it every time;

The line with the gmail email adress is more interesting…

give me any solutions
please, i trying from last three days

You need to provide more logs because the last 2 logs are bots. Nothing wrong with it… The does not include the log that explains the error.
