[SOLVED] SSL error when sending email with nodemailer

when sending a mail (nodemailer) with secure set to true:

    const transporter = nodemailer.createTransport({
        host: process.env.SMTP_SERVER_HOST,
        port: process.env.SMTP_SERVER_PORT,
        secure: true,
        auth: {
            user: process.env.SMTP_USERNAME,
            pass: process.env.SMTP_PASSWORD,
        },
    });

my appwrite function exits with Error: 139628785929072:error:1408F10B:SSL routines:ssl3_get_record:wrong version number:../deps/openssl/openssl/ssl/record/ssl3_record.c:332: sending the mail with secure turned off works without issues. do you have any fix for sending the mail with secure turned on?

This is cloud or self-hosted?

the latter

Are you using TLS ports?

There should be ports from your provider to use without TLS and others to use with TLS. This looks like you're using a port that doesn't supports TLS by your provider

im running appwrite behind a reverse proxy and the traffic goes over https to the http port of appwrite

Oh, I see. But you're self-hosting the SMTP server?

nope

No idea then. From what I'm seeing on Google, looks like others users solved it by changing ports but also others solved it by changing TLS version

found my issue:

this is from the node mailer docs: secure – if true the connection will use TLS when connecting to server. If false (the default) then TLS is used if server supports the STARTTLS extension. In most cases set this value to true if you are connecting to port 465. For port 587 or 25 keep it false

my port for smpt is indeed 587

and uses STARTTLS

I see. Hope that solves the issue

I supposed it was related to some config related to ports

i also thought so, thanks for the help

Tell me if that's the final solution and it works

seems like it
