Can you put this in your config/config.php in order to get more details in your logs: ``` /** * Enable SMTP class debugging. */ 'mail_smtpdebug' => true, ``` If you control the mail server as well, you can check the logfiles there as well. ---

Are you sending through php? Or smtp? The new log-option should create entries in your Nextcloud-logfile. ---

I was using the cert.pem instead of the fullchain.pem (From letsencrypt) on my mailserver and got this error. You can check your emailserver here: [www.sslshopper.com](https://www.sslshopper.com/ssl-checker.html#hostname=smtp.gmail.com:465) Working without problem using the fullchain.pem ---

For those who would like to use [smtp.gmail.com](http://smtp.gmail.com) (after setting at [myaccount.google.com](http://myaccount.google.com) ), port 587 did not work but port 465 worked when “Encryption: SSL/TLS” is chosen at “Email server” setting of Nextcloud. In fact, [www.sslshopper.com/ssl-checker.html#hostname=smtp.gmail.com:587](http://www.sslshopper.com/ssl-checker.html#hostname=smtp.gmail.com:587) showed “No SSL”, but 465 displayed its certificate info. ---
