subject = 'python email test'
smtpserver = 'smtp.163.com'
username = '***'
password = '***'
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()

#构造附件
att = MIMEText(open('h:\\python\\1.jpg', 'rb').read(), 'base64', 'utf-8')
att["Content-Type"] = 'application/octet-stream'
att["Content-Disposition"] = 'attachment; filename="1.jpg"'
msgRoot.attach(att)
smtp = smtplib.SMTP()
smtp.connect('smtp.163.com')

username = '***'
password = '***'
msg = MIMEText('你好','text','utf-8')
msg['Subject'] = subject
smtp = smtplib.SMTP()
smtp.connect('smtp.163.com')
smtp.login(username, password)
smtp.sendmail(sender, receiver, msg.as_string())
smtp.quit()
各种元素都包含的邮件
#!/usr/bin/env python3
#coding: utf-8
import smtplib
from email.mime.multipart import MIMEMultipart

sender = '***'
receiver = '***'
subject = 'python email test'
smtpserver = 'smtp.163.com'
username = '***'
password = '***'
# Create message container - the correct MIME type is multipart/alternative.
msg = MIMEMultipart('alternative')
msg['Subject'] = "Link"
# Create the body of the message (a plain-text and an HTML version).
text = "Hi!\nHow are you"
html = """\
<html>
<head></head>
<body>
<p>Hi!<br>

</p>
</body>
</html>
"""
# Record the MIME types of both parts - text/plain and text/html.
part1 = MIMEText(text, 'plain')
part2 = MIMEText(html, 'html')
# Attach parts into message container.
# According to RFC 2046, the last part of a multipart message, in this case
# the HTML message, is best and preferred.
msg.attach(part1)
msg.attach(part2)
#构造附件
att = MIMEText(open('h:\\python\\1.jpg', 'rb').read(), 'base64', 'utf-8')
att["Content-Type"] = 'application/octet-stream'

msg.attach(att)
smtp = smtplib.SMTP()
smtp.connect('smtp.163.com')

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.ehlo()
smtp.starttls()
smtp.ehlo()
smtp.set_debuglevel(1)
smtp.login(username, password)
