[风一样汉子]

提示错误：
raise SMTPServerDisconnected("Connection unexpectedly closed")
smtplib.SMTPServerDisconnected: Connection unexpectedly closed

import smtplib
from email.mime.text import MIMEText

me = '[e-mail]'
pw = 'qweas123098'
you =['[e-mail]']

msg =MIMEText('hello, send by Python...', 'plain', 'utf-8')
msg['Subject'] = 'The contents of %s'
msg['From'] = me
msg['To'] = you

server  = smtplib.SMTP('smtp.163.com',465)
server.starttls()
server .login(me,pw)
server .sendmail(me, [you], msg.as_string())
server .quit()
