TLS error, trying plaintext

[kkzliu]

I encountered a tls error when sending an email to mail.163.com using RainLoop webmail. I'm not sure what the problem is.

How to solve it? thanks

error:

Thank you, I have updated the latest code for the master, but this error still persists. The SMTP encryption configuration for rainloop webmail is set to SSL/TLS
