import smtplib
from email.mime.text import MIMEText
from email.header import Header

sender = 'fengyiru6369@163.com'
receiver = '1194150169@qq.com'
subject = 'python email test'
smtpserver = 'smtp.163.com'
username = 'fengyiru6369@163.com'
password = 'XXXXXXXX'  # 是授权密码，而不是登录密码

msg = MIMEText('你好', 'text', 'utf-8')  # 中文需参数‘utf-8’，单字节字符不需要
msg['Subject'] = Header(subject, 'utf-8')

smtp = smtplib.SMTP()
smtp.connect('smtp.163.com')
smtp.login(username, password)
smtp.sendmail(sender, receiver, msg.as_string())
smtp.quit()

只赋值了msg['Subject'], 没有赋值msg['From'], msg['To']，导致出现554情况，更改了后就好了。

注意MIMEText初始化的时候，中文的第二个参数要用'plain'，我用'text',中文就显示不出来。

msg['From'] 中人名为Tim，会和下面对应起来。
