It seems to me that is just a success report not an error.
As the notice says : The email was sent successfully with no errors.

If so, what does the logs in server error log means?
(The notice in test email is just used to show that the function is working properly.)

The main problem is in the first image of the post instead of the last.

 

[Old Nick]

Remove them from log and do a new e-mail test.

Remove them from log and do a new e-mail test.

just did it last day, the result was successful.

but today it appears again...

ErrorException: Email to liu_x_di@163.com from service@uotan.cn failed: [E_WARNING] fwrite(): SSL operation failed with code 1. OpenSSL Error messages: error:1409E10F:SSL routines:ssl3_write_bytes:bad length

I don't mean to sound like an arse... but the very fact that you have a CN domain and most likely are hosted in their environ may have an issue with their "wonderful" blocking of services.

New users get a warning about the "large number of visits"... so mayhap you are having hosting issues?

The blocking notice is used to prevent our site from network attacks. I didn't put it on the mail server.

So I think hosting issues may not be the factor of the error.

I have a direction of the solution, but I'm not sure whether it is feasible.
Is the problem linked with TLS settings? Our main domain is TLS 1.2(uotan.cn), but the mail server is TLS 1.3(mail.uotan.cn). Should I turn my TLS version to the same?

If possible... it's usually better to use the newer standards.
