首先Python导入smtp模块和email.mime.text import MIMEText

sender = “xxx@163.com” password="zzz"

receiver = "yyy@163.com"

Mail_Host = "smtp.163.com"

message = MIMEText(content,_subtype="plain",_charset="utf-8")//定义发送文本的格式

message['Subject'] = sub

message[‘From’]=user

message['To']=";".join(receiver)

server=smtplib.SMTP(Mail_Host,25) /server=smtplib.SMTP server.connect(Mail_Host,25) 使用这两种方法链接SMTP

server.login(sender,password)

server.sendmail(sender,receiver,message.as_string())

server.close()

若产生550错误的话应该是得将邮箱进行授权，将@163.com->设置->客户端密码授权
