Hello

The error SMTP Error: Could not authenticate is back on D896 + rc4 version of the module.

Weird thing is if I set the sender as PHP mail default, test email is received with the watchdog error.

Hello. I'm also having Authentication Error after upgrading to Drupal Version 8.9.6.

drupal/smtp 1.0.0

drupal/core 8.9.6

Connection Failed. Error #2: stream_socket_enable_crypto(): SSL operation failed with code 1. OpenSSL Error messages: error:1416F086:SSL routines:tls_process_server_certificate:certificate verify failed [/app/vendor/phpmailer/phpmailer/src/SMTP.php line 454]

PHP’s OpenSSL extension rejected the mail server’s certificate — typically because:

  1. The certificate is self-signed or issued by an untrusted CA.
  2. The hostname in the certificate doesn’t match the SMTP host you’re connecting to.
  3. The server’s certificate chain is incomplete (missing intermediate CA certs).
  4. Your container or PHP environment is missing CA certificates.

I would need more information to know the cause. There has not been activity for 5 years, so I am closing the issue.
