Question

我的django邮件有问题，显然我可以使用gmail帐户发送电子邮件，没有问题，但是我无法从自定义域电子邮件发送任何电子邮件。有一个小问题，我的SMTP SSL电子邮件在本地有效，但是在EC2实例上加载后它什么也没发送。

我尝试从SMTPSSL更改为仅SMTP，但仍然无法正常工作，我也尝试了一个heroku实例，但是再次，heroku实例甚至没有从gmail作为EC2实例发送。

ACCOUNT_EMAIL = os.environ['ACCOUNT_EMAIL']
ACCOUNT_PASSWORD = os.environ['ACCOUNT_PASSWORD']
# EMAIL_PROVIDER = 'smtp.gmail.com' //gmail configurations
# EMAIL_SERVER_PORT = 587
EMAIL_PROVIDER = 'krishna.hosting-mexico.net'
EMAIL_SERVER_PORT = 465
SECURITY_EMAIL_SENDER = ACCOUNT_EMAIL


def send_driver_welcome_email(user_email):
    from_email_address = EMAIL
    from_email_address_password = PASSWORD
    htmly     = get_template('driver_welcome_email.html')

    message = MIMEMultipart('alternative')
    message['Subject'] = 'Bienvenido a TAXI 2.0'
    message['From'] = from_email_address
    message['To'] = user_email

    html_content = htmly.render(None)

    part1 = MIMEText(html_content, 'html')

    message.attach(part1)

    server = smtplib.SMTP(EMAIL_PROVIDER, EMAIL_SERVER_PORT)
    #server = smtplib.SMTP_SSL(EMAIL_PROVIDER, EMAIL_SERVER_PORT) //This works locally
    server.ehlo()
    server.starttls()
    server.login(from_email_address, from_email_address_password)
    server.sendmail(from_email_address, user_email, message.as_string())
    server.quit()

在我的控制台上，我得到了错误：（今天的测试）

...

我不知道为什么会这样，而且Google并没有太大帮助，因为很多页面建议使用SES，但是我没有使用它的兴趣，因为我想使用我的网站域和无需为亚马逊支付任何应有的费用。

因此，如果有人遇到相同的问题，只需将端口更改为587，即可在Heroku和EC2实例上正常工作。

此外，请记住，我的解决方案不会将已发送的电子邮件复制到域的“发送”文件夹中。

为什么我的EC2可以通过Gmail发送电子邮件，但不能从自定义域发送电子邮件？
