SSL3 Errror with outlook.com

[dcbartlett]

Hi I was setting up nodemailer to work with outlook.com and got the following error.

Error : 3074565888:error:1408F10B:SSL routines:SSL3_GET_RECORD:wrong version number:../deps/openssl/openssl/ssl/s3_pkt.c:337: 

This is the config i was using.

var smtpTransport = nodemailer.createTransport('SMTP', {
    host: 'smtp.live.com', // hostname
    secureConnection: false, // use SSL
    port: 587, // port for secure SMTP
    auth: {
        user: '********@outlook.com',
        pass: '********'
    }
});

Hi, which version of Nodemailer and node are you using? This could be duplicate of https://github.com/andris9/Nodemailer/issues/155

[dcbartlett]

node: v0.10.11
nodemailer: 0.4.4

To get Hotmail running you should either not define the host and port by yourself but use a service option

{
    service: "hotmail",
    auth: {
        user: '********@outlook.com',
        pass: '********'
    }
}

Or alternatively add an addtional tls option

{
    host: 'smtp.live.com', // hostname
    secureConnection: false, // use SSL
    port: 587, // port for secure SMTP
    auth: {
        user: '********@outlook.com',
        pass: '********'
    },
    tls:{
        ciphers:'SSLv3'
    }
}

I am having the same issue. I am connecting to a private email server. Here is my configuration:

var smtpTransport = nodemailer.createTransport("SMTP", {
    host: "***.***.***.***",
    secureConnection: true,
    port: 465,
    auth: {
            user: "****",
            pass: "****"
    },
    tls: {
            ciphers:'SSLv3'
    }
});

I receive the same error as the OP:

{ [Error: 140735294948112:error:1408F10B:SSL routines:SSL3_GET_RECORD:wrong version number:../deps/openssl/openssl/ssl/s3_pkt.c:337:] stage: 'auth' }

I can successfully connect to the server via openssl:

openssl s_client -crlf -connect ***.***.***.***:465

When I connect this way, the server responds with:

...
New, TLSv1/SSLv3, Cipher is DHE-RSA-AES256-GCM-SHA384
Server public key is 2048 bit
Secure Renegotiation IS supported
Compression: NONE
Expansion: NONE
SSL-Session:
    Protocol  : TLSv1.2
    Cipher    : DHE-RSA-AES256-GCM-SHA384
...

@andris9 What does the tls: { ciphers:'SSLv3' } do?

I am trying to understand the reason behind adding the tls option

setting the port from 587 to 465 solved my problem.
Error while port was 587:

{ [Error: 140525118728000:error:1408F10B:SSL routines:ssl3_get_record:wrong version number:../deps/openssl/openssl/ssl/record/ssl3_record.c:252:
] code: 'ECONNECTION', command: 'CONN' }

After changed the port to 465:
Email sent: 250 Requested mail action okay, completed: id=0MC4m6-1gvUQI3jdI-008qAi

ran into this issue, discovered i was using an old version of nodemailer. updating to the latest version and removing a bunch of other outdated code fixed it for me

add secure: (String(config.port)==="465") to the options.

config.port should be the same port that you are trying to connect. use 587 for Outlook, Hotmail etc.,

[mscbpi]

live.com a bit different from office365 enterprise and we get same error. 587 is not available on MX record for direct send. It used TLS on 25.

The smtp relay host with auth (user licence needed) would be smtp.office365.com. We don't use this option.

The other option is direct send to MX server (another DNS record) and a connector to allow relay based on IP of the sender.

This is what we chose. It used to work. It uses port 25 only.
