本文实例为大家分享了Python smtplib发送邮件功能的具体代码，供大家参考，具体内容如下

解决之前版本的问题，下面为最新版

 send() 

配置文件emailConfig.ini

路径要与程序对应

;login_username : 登陆发件人用户名
;login_password : 登陆发件人密码
;host:port : 发件人邮箱对应的host和端口，如：smtp.163.com:25 和 smtp.qq.com:465
;receiver : 收件人，支持多方发送，格式（注意英文逗号）： 123456789@163.com,zxcvbnm@qq.com 

[SMTP]
login_username = johnny@163.com
login_password = johnny
host = smtp.163.com
port = 25
receiver = johnny1@qq.com,johnny2@163.com,johnny3@gmail.com

if __name__=="__main__":

 text = "johnny'lab test"

 host = 'smtp.163.com'
 username = 'qqq@163.com'
 password = 'qqq'
 send_email_text(sender,receiver,host,subject,text,filename) 

已测试通过，使用Header并没有变成“头”，故未使用

若能解决附件格式为（html、jpg、png）在邮箱附件中格式不为“bin”的请联系我，希望此对大家有所帮助，谢谢（已解决，见上面最新版）
