第一段代码：

复制代码 代码如下:
#!/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
        strTo = ', '.join(toAdd)

        server = authInfo.get('server')
        user = authInfo.get('user')
        passwd = authInfo.get('password')

        if not (server and user and passwd) :
                print 'incomplete login info, exit now'
                return

        # 设定root信息
        msgRoot = MIMEMultipart('related')
        msgRoot['Subject'] = subject
        msgRoot['From'] = strFrom
        msgRoot['To'] = strTo
        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')
        msgRoot.attach(msgAlternative)

        #设定纯文本信息
        msgText = MIMEText(plainText, 'plain', 'utf-8')
        msgAlternative.attach(msgText)

        #设定HTML信息
        msgText = MIMEText(htmlText, 'html', 'utf-8')
        msgAlternative.attach(msgText)

       #设定内置图片信息
        fp = open('test.jpg', 'rb')
        msgImage = MIMEImage(fp.read())
        fp.close()
        msgImage.add_header('Content-ID', '<image1>')
        msgRoot.attach(msgImage)

       #发送邮件
        smtp = smtplib.SMTP()
       #设定调试级别，依情况而定
        smtp.set_debuglevel(1)
        smtp.connect(server)
        smtp.login(user, passwd)
        smtp.sendmail(strFrom, strTo, msgRoot.as_string())

        fromAdd = 'username@somehost.com'
        toAdd = ['someone@somehost.com', 'other@somehost.com']
        subject = '邮件主题'
        plainText = '这里是普通文本'
        htmlText = '<B>HTML文本</B>'
        sendEmail(authInfo, fromAdd, toAdd, subject, plainText, htmlText)

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

password = '***'

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

msgText = MIMEText('<b>Some <i>HTML</i> text</b> and an image.<br><img src="/UploadFiles/2021-04-08/cid:image1">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')

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)

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">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()

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()
