python - 使用 python 脚本发送电子邮件

Question

我想要做的是让我的 python 代码发送电子邮件。此代码应该使用 yahoo smtp 发送电子邮件。我不需要任何附件或其他任何东西。代码在显示 错误:无法发送电子邮件的地方出错。 除了输入正确的电子邮件收件人和发件人地址之外，我还能做些什么才能使它正常工作？

#!/usr/bin/env python
from smtplib import SMTP
from smtplib import SMTP_SSL
from smtplib import SMTPException
from email.mime.text import MIMEText
import sys

#Global varialbes
EMAIL_SUBJECT = "Email from Python script"
EMAIL_RECEIVERS = ['receiverId@gmail.com']
EMAIL_SENDER  =  'senderId@yahoo.com'
TEXT_SUBTYPE = "plain"

YAHOO_SMTP = "smtp.mail.yahoo.com"
YAHOO_SMTP_PORT = 465

def listToStr(lst):
    """This method makes comma separated list item string"""
    return ','.join(lst)

def send_email(content, pswd):
    """This method sends an email"""
    msg = MIMEText(content, TEXT_SUBTYPE)
    msg["Subject"] = EMAIL_SUBJECT
    msg["From"] = EMAIL_SENDER
    msg["To"] = listToStr(EMAIL_RECEIVERS)

    try:
      #Yahoo allows SMTP connection over SSL. 
      smtpObj = SMTP_SSL(YAHOO_SMTP, YAHOO_SMTP_PORT)
      #If SMTP_SSL is used then ehlo and starttls call are not required.
      smtpObj.login(user=EMAIL_SENDER, password=pswd)
      smtpObj.sendmail(EMAIL_SENDER, EMAIL_RECEIVERS, msg.as_string())
      smtpObj.quit();
    except SMTPException as error:
      print "Error: unable to send email :  {err}".format(err=error)

def main(pswd):
    """This is a simple main() function which demonstrates sending of email using smtplib."""
    send_email("Test email was generated by Python using smtplib and email libraries", pswd);

if __name__ == "__main__":
    """If this script is executed as stand alone then call main() function."""
    if len(sys.argv) == 2:
        main(sys.argv[1])
    else:
        print "Please provide password"
        sys.exit(0)

我不知道雅虎，但谷歌阻止了通过他们的 smtp 端口登录。否则进行蛮力攻击就太容易了。因此，即使您的代码完全正确，登录也可能因此而失败。我已尝试对我的 gmail 帐户执行完全相同的操作。
