第一段代码：


#!/usr/bin/python
# -*- coding: utf-8 -*-
import email
import mimetypes
from email.MIMEMultipart import MIMEMultipart
from email.MIMEText import MIMEText
from email.MIMEImage import MIMEImage
import smtplib
def sendEmail(authInfo, fromAdd, toAdd, subject, plainText, htmlText):
 strFrom = fromAdd

 msgRoot.preamble = 'This is a multi-part message in MIME format.'
 # Encapsulate the plain and HTML versions of the message body in an
 # 'alternative' part, so message agents can decide which they want to display.
 msgAlternative = MIMEMultipart('alternative')

文件形式的邮件


#!/usr/bin/env python3 
#coding: utf-8 
import smtplib 
from email.mime.text import MIMEText 
from email.header import Header sender = '***' 
receiver = '***' 
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()

HTML形式的邮件


#!/usr/bin/env python3
#coding: utf-8
import smtplib
from email.mime.text import MIMEText
sender = '***'
receiver = '***'
subject = 'python email test'
smtpserver = 'smtp.163.com'
username = '***'
password = '***'
msg = MIMEText('<html><h1>你好</h1></html>','html','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()

带图片的HTML邮件

username = '***'
password = '***'
msgRoot = MIMEMultipart('related')
msgRoot['Subject'] = 'test message'
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())

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()

群邮件


#!/usr/bin/env python3
#coding: utf-8
import smtplib
from email.mime.text import MIMEText
sender = '***'
receiver = ['***','****',……]
subject = 'python email test'
smtpserver = 'smtp.163.com'

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>

 How are you?<br>
 Here is the <a rel="nofollow noopener noreferrer" href="http://www.python.org">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')

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
sender = '***'
receiver = '***'
subject = 'python email test'
smtpserver = 'smtp.163.com'
username = '***'
password = '***'
msg = MIMEText('你好','plain','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)
smtp.sendmail(sender, receiver, msg.as_string())
smtp.quit()
