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()

msgText = MIMEText('<b>Some <i>HTML</i> text</b> and an image.<br><img src="cid:image1"><br>good!','html','utf-8') 
msgRoot.attach(msgText) 
 
fp = open('h:\\python\\1.jpg', 'rb') 
msgImage = MIMEImage(fp.read()) 
fp.close() 
 
msgImage.add_header('Content-ID', '<image1>') 
msgRoot.attach(msgImage) 
 
smtp = smtplib.SMTP() 
smtp.connect('smtp.163.com') 
smtp.login(username, password) 
smtp.sendmail(sender, receiver, msgRoot.as_string()) 
smtp.quit()

smtpserver = 'smtp.163.com' 
username = '***' 
password = '***' 
 
msgRoot = MIMEMultipart('related') 
msgRoot['Subject'] = 'test message' 
 
#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') 
smtp.login(username, password) 
smtp.sendmail(sender, receiver, msgRoot.as_string()) 
smtp.quit()

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 
from email.mime.text import MIMEText 
from email.mime.image import MIMEImage 
 
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?\nHere is the link you wanted:\nhttp://www.python.org" 
html = """\ 
<html> 
 <head></head> 
 <body> 
 <p>Hi!<br> 
 How are you?<br> 
 Here is the <a href="http://www.python.org" rel="external nofollow" >link</a> you wanted. 
 </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' 
att["Content-Disposition"] = 'attachment; filename="1.jpg"' 
msg.attach(att) 
 
smtp = smtplib.SMTP() 
smtp.connect('smtp.163.com') 
smtp.login(username, password) 
smtp.sendmail(sender, receiver, msg.as_string()) 
smtp.quit()

基于SSL的邮件

#!/usr/bin/env python3 
#coding: utf-8 
import smtplib 
from email.mime.text import MIMEText 
from email.header import Header

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