Python smtplib实现发送邮件功能

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

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）： [e-mail],[e-mail] 

[SMTP] 
login_username = [e-mail] 
login_password = johnny 
host = smtp.163.com 
port = 25 
receiver = [e-mail],[e-mail],[e-mail]

之前版本出现的问题：

 host = 'smtp.163.com' 
 username = '[e-mail]' 
 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）
