如何使用Outlook的SMTP服务器发送电子邮件?

I want to send an email using Outlook servers, but I'm getting an error 504 5.7.4 Unrecognized authentication type

Here's the snippet.

func sendEmail() {
    server := "smtp-mail.outlook.com
    port := 587
    user := "foo@outlook.com"
    from := user
    pass := "foobar"
    dest := "bar@gmail.com"

    auth := smtp.PlainAuth("", user, pass, server)

    to := []string{dest}

    msg := []byte("From: " + from + "
" +
        "To: " + dest + "
" +
        "Subject: Test outlook
" +
        "OK")

    endpoint := server + ":" + port
    err := smtp.SendMail(endpoint, auth, from, to, msg)
    if err != nil {
        log.Fatal(err)
    }
}

If instead of sending the email using outlook, I use gmail, it works fine.

In Python, I can send the email using outlook with the following code:

    server = smtplib.SMTP(server, port)
    server.starttls()
    server.login(user, password)
    server.sendmail(from, to, msg)
    server.quit()

So I guess I'm missing something in my Go code. According to the doc, SendMail switches to TLS, so that shouldn't be the issue.

    auth := smtp.PlainAuth("", user, pass, server)
    

    This is using the authentication method PLAIN. Unfortunately smtp-mail.outlook.com does not support this authentication method:

    > EHLO example.com
    < 250-AM0PR10CA0007.outlook.office365.com Hello ...
    < 250- ...
    < 250-AUTH LOGIN XOAUTH2
    

    Thus, only LOGIN and XOAUTH2 are supported as authentication methods.

    server.login(user, password)
    

    Python supports LOGIN so it will succeed.

    Golang smtp does not support LOGIN. But this gist seems to provide a working fix by adding this missing authentication method.
