通过本地Exim MTA在python中发送电子邮件

我试图在我的Arch Linux VPS上创建一个自动系统,该系统会将每月HTML格式的报告发送到我的电子邮箱。我决定使用python作为编程语言,但我发现自己陷入了困境。

在下面的代码中,您会发现我使用SMTPlib来构建和发送消息。

import smtplib
from email.mime.multipart import MIMEMultipart
from email.mime.text import MIMEText


def py_mail(SUBJECT, BODY, TO, FROM):
    """"With this function we send out our HTML email"""

    # Create message container - the correct MIME type is multipart/alternative here!
    MESSAGE = MIMEMultipart('alternative')
    MESSAGE['subject'] = SUBJECT
    MESSAGE['To'] = TO
    MESSAGE['From'] = FROM
    MESSAGE.preamble = """"Your reader does not support the report format. Please visit 
                            us <a href="https://my-website.nl">online</a>!"""

    # Record the MIME type text/html
    HTML_BODY = MIMEText(BODY, 'html')

    # Attach parts into message container
    MESSAGE.attach(HTML_BODY)

    # Create SMTP object
    server = smtplib.SMTP(host='localhost', port=587)

    # Print debugging output when testing
    if __name__ == '__main__':
        server.set_debuglevel(1)

    # The actual sending of the email
    try:
        server.starttls()
        server.sendmail(FROM, [TO], MESSAGE.as_string())
        server.quit()
    except smtplib.SMTPException as error:
        print("Error: unable to send mail : {err}".format(err=error))


if __name__ == '__main__':
    """Executes if the script is run as main script (for testing purposes)"""

    email_content = """"
    <head>
        <link href="https://fonts.googleapis.com/css?family=Open+Sans+Condensed:300" rel="stylesheet">
        <meta charset="UTF-8">
        <title>TestMail</title>

        <style>
            h1 {
                position: absolute;
                top: 50%;
                left: 50%;
                -webkit-transform: translate(-50%, -50%);
                -moz-transform: translate(-50%, -50%);
                -ms-transform: translate(-50%, -50%);
                -o-transform: translate(-50%, -50%);
                transform: translate(-50%, -50%);
                font-family: "Open Sans Condensed", sans-serif;
                font-size: 3em;

            }
        </style>

    </head>
    <body>
        <h1>'tis but a scratch</h1>
    </body>
    """

    TO = 'to-email@website.com'
    FROM = 'from-email@website.com'

    py_mail("Test email onderwerp", email_content, TO, FROM)

但是一旦我运行脚本,我就会收到以下错误:

  

ConnectionRefusedError:[Errno 111]拒绝连接

我在我的服务器上运行Exim作为本地的仅发送MTA。通过命令行发送电子邮件没有问题。只有在我尝试使用Python连接问题时才会出现问题。

如果有人能帮助我,那就太棒了。提前致谢

答案 0 :(得分:-1)

您是否真的在localhost端口587上运行SMTP服务器?尝试端口25 - 它是SMTP的标准端口。 587适用于SSL / TLS,但您必须为此配置SMTP。

如果您确定它必须真的是端口587 - 请检查防火墙设置。
