2020-08-12

使用python SSL SMTP 发送邮件

以163 SSL SMTP服务为例:163开通SMTP服务和获取授权码

import smtplib
from email.mime.text import MIMEText
from email.utils import formataddr
import traceback

# 第三方 SMTP 服务
SENDER = "xxxxx@163.com"  # 用户名
MAIL_PASS = "XXXXXXXXXXXXXX"  # 授权码,需要手动申请,
RECEIVERS_LIST = ['xxxxxx@163.com', 'xxxxxxx@qq.com']  # 邮件收件人


def send_mail(mail_content: str, subject: str, smtp_server_addr: str = "smtp.163.com", smtp_server_port: int = 465,
              sender=SENDER, mail_pass=MAIL_PASS, receivers_list=None):
    """
    发送邮件接口,默认发送到163邮件
    :param receivers_list: 邮件接收列表,eg:['xxxx@qq.com', 'ttttt@qq.com']
    :param mail_pass: 密钥
    :param sender: 发送邮件人
    :param mail_content: 邮件内容
    :param subject: 邮件主题
    :param smtp_server_addr: 默认163 smtp地址
    :param smtp_server_port: 默认163 smtp ssl端口
    :return: True表示成功,False表示失败
    """
    if receivers_list is None:
        receivers_list = RECEIVERS_LIST
    try:
        msg = MIMEText(mail_content, 'plain', 'utf-8')
        msg['From'] = formataddr((sender.split('@')[0], sender))  # 括号里的对应发件人邮箱昵称、发件人邮箱账号
        msg['To'] = ','.join([formataddr((receiver.split('@')[0], receiver))
                              for receiver in receivers_list])  # 括号里的对应收件人邮箱昵称、收件人邮箱账号
        msg['Subject'] = subject  # 邮件的主题,也可以说是标题
        server = smtplib.SMTP_SSL(smtp_server_addr, smtp_server_port)  # 发件人邮箱中的SMTP服务器,端口是25
        server.login(sender, mail_pass)  # 括号中对应的是发件人邮箱账号、邮箱密码
        server.sendmail(sender, receivers_list, msg.as_string())  # 括号中对应的是发件人邮箱账号、收件人邮箱账号、发送邮件
        server.quit()  # 关闭连接
        return True
    except Exception:  # 如果 try 中的语句没有执行,则会执行下面的 ret=False
        traceback.print_exc()
        return False

if __name__ == '__main__':
    if send_mail(subject="xxxx", content="xxx"):
        print('发送成功!')
    else:
        print('发送失败!')
