基于Python实现邮件发送

Posted 2020-08-19

实现功能：

邮件发送，支持文字，音频文件，文本文件，图形文件，应用程序及其它类型文件的发送；

支持不同的邮箱；

支持一次性往多个邮箱发送；

支持一次性发送n个附件；

支持中文命名的附件发送；

 

mail.conf配置:

[SMTP]

login_user = [email protected]

login_pwd = xxxxx

from_addr =  [email protected]

to_addrs = [‘[email protected]‘,‘[email protected]‘]

host = smtp.163.com

port = 25

说明：不同类型的邮箱(发件人邮箱)，需要修改配置文件为对应的host和端口

smtp.163.com:25

smtp.qq.com:465

# -*- coding:GBK -*-
