Can't send email

[ahmaddanial]

Hello, @maki

Based on the error that we are seeing in mattermost.log, the server is complaining about unencrypted connection:

@maki

Connection unsuccessful: SendMail: Failed to authenticate on SMTP server, unencrypted connection

Can you please confirm which SMTP setting you are using based on the sample configuration we shared in the documentation?

We will then cross check it with the right SMTP connection security (None / TLS / STARTTLS), port, and SMTP server before we dig deeper into the respective error.

For additional context, I am also troubleshooting another issue here related to the first record does not look like a TLS handshake error:

• TLS Connection Error SendMail tls: first record does not look like a TLS handshake
