Hi, thanks for getting in touch.

Looking through this and #12387 and what has already been tried, I wonder if specifying the accepted encryption method would help. Could you give this a go for testing purposes? In app.php

'components' => [
    'mailer' => function() {
        $mailer = Craft::createObject(App::mailerConfig());
        $stream = $mailer->getTransport()->getStream();
        $stream->setStreamOptions([
            'ssl' => [
                'crypto_method' => \STREAM_CRYPTO_METHOD_TLSv1_2_CLIENT
            ]
        ]);
        return $mailer;
    },
],

Various options for the crypto_method are listed, e.g. here: https://www.php.net/manual/en/function.stream-socket-enable-crypto.php and end with _CLIENT

Thanks for your help!

I trid all crypto_method , got the same error message. I asked the email server administrator about the relevant records, they had received our request, but could not create the TLS handshake.

@ivesho can you connect to any other SMTP server on the same box you’re getting that error on?

If not, that would indicate something misconfigured on the box Craft is installed on (openssl/tls/ssl/etc.).

If you can connect to another server, that would indicate something similarly misconfigured on the mail server side (and the logs from the server administrator would be necessary to debug).
