本文实例为大家分享了python实现邮件自动发送的具体代码，供大家参考，具体内容如下

case 1：纯文本和HTML文件发送

# -*- coding: UTF-8 -*-import smtplibimport tracebackfrom email.mime.text import MIMETextfrom email.mime.multipart import MIMEMultipartdef sendmail(subject,msg,toaddrs,fromaddr,smtpaddr,password): ''' @subject:邮件主题 @msg:邮件内容 @toaddrs:收信人的邮箱地址 @fromaddr:发信人的邮箱地址 @smtpaddr:smtp服务地址，可以在邮箱看，比如163邮箱为smtp.163.com @password:发信人的邮箱密码 ''' mail_msg = MIMEMultipart() if not isinstance(subject,unicode): #过滤或者不过滤貌似没啥影响  subject = unicode(subject, 'utf-8') mail_msg['Subject'] = subject mail_msg['From'] =fromaddr mail_msg['To'] = ','.join(toaddrs) mail_msg.attach(MIMEText(msg, 'plain', 'utf-8')) #f发送文本文件 #mail_msg.attach(MIMEText(msg, 'html', 'utf-8')) #发送html格式邮件 try:  s = smtplib.SMTP()  s.connect(smtpaddr) #连接smtp服务器  s.login(fromaddr,password) #登录邮箱  s.sendmail(fromaddr, toaddrs, mail_msg.as_string()) #发送邮件  s.quit()  print "邮件发送成功！" except Exception,e:  print "Error: unable to send email"  print traceback.format_exc()if __name__ == '__main__': fromaddr = "h******[email protected]" smtpaddr = "smtp.126.com" toaddrs = ["83****[email protected]","h******[email protected]"] subject = "Hello,我是邮件主题" password = "不能告诉你" #msg = "Hello,我是邮件内容 !!!" msg=""" <p>Python 邮件发送测试...</p> <p><a href="http://www.runoob.com" >这是一个链接</a></p> """ sendmail(subject,msg,toaddrs,fromaddr,smtpaddr,password)

case 2.添加附件：发送带附件的邮件，首先要创建MIMEMultipart()实例，然后构造附件，如果有多个附件，可依次构造，最后利用smtplib.smtp发送。

# -*- coding: UTF-8 -*-# 如何添加附件import osimport smtplibimport tracebackfrom email.mime.text import MIMETextfrom email.mime.multipart import MIMEMultipartos.chdir("C:\\Users\\h****m\\Desktop\\Auto_email")def sendmail(subject,msg,toaddrs,fromaddr,smtpaddr,password): ''' @subject:邮件主题 @msg:邮件内容 @toaddrs:收信人的邮箱地址 @fromaddr:发信人的邮箱地址 @smtpaddr:smtp服务地址，可以在邮箱看，比如163邮箱为smtp.163.com @password:发信人的邮箱密码 ''' mail_msg = MIMEMultipart() if not isinstance(subject,unicode): #过滤或者不过滤貌似没啥影响  subject = unicode(subject, 'utf-8') mail_msg['Subject'] = subject mail_msg['From'] =fromaddr mail_msg['To'] = ','.join(toaddrs) #mail_msg.attach(MIMEText(msg, 'plain', 'utf-8')) #f发送文本文件 mail_msg.attach(MIMEText(msg, 'html', 'utf-8')) #发送html格式邮件  #构造附件1 att1=MIMEText(open("test_file1.txt",'rb').read(),'base64','utf-8') #注意：直接读取中文文件名会报错  att1["Content-Type"] = 'application/octet-stream' att1["Content-Disposition"] = 'attachment; filename="test_file1.txt"' mail_msg.attach(att1)   #构造附件2：添加中文附件名 att2=MIMEText(open(u'测试文件2.docx','rb').read(),'base64','utf-8') att2["Content-Type"] = 'application/octet-stream' att2["Content-Disposition"] = 'attachment; filename="test_file2.docx"' mail_msg.attach(att2)  try:  s = smtplib.SMTP()  s.connect(smtpaddr) #连接smtp服务器  s.login(fromaddr,password) #登录邮箱  s.sendmail(fromaddr, toaddrs, mail_msg.as_string()) #发送邮件  s.quit()  print "邮件发送成功！" except Exception,e:  print "Error: unable to send email"  print traceback.format_exc()if __name__ == '__main__': fromaddr = "h****[email protected]" smtpaddr = "smtp.126.com" toaddrs = ["83****[email protected]","h****[email protected]"] subject = "Hello,我是邮件主题" password = "不能告诉你" #msg = "Hello,我是邮件内容 !!!" msg=""" <p>Python 邮件发送测试...</p> <p><a href=http://www.runoob.com >这是一个链接</a></p> """ sendmail(subject,msg,toaddrs,fromaddr,smtpaddr,password)

case 3: 发送图片(容易被判别为垃圾邮件，导致：SMTPDataError: (554, 'DT:SPM 126……错误)

# -*- coding: utf-8 -*-fromaddr = "h****[email protected]"smtpaddr = "smtp.126.com"toaddrs = ["83****[email protected]","h****[email protected]"]subject = "Hello,我是邮件主题"password = "不能告诉你"#test3msg = """<p>Python 邮件发送添加图片测试...</p><p><a href="http://www.runoob.com" >菜鸟教程链接</a></p><p>图片演示：</p><p><img src="https:/article/cid:image1"></p>"""import osimport smtplibfrom email.mime.text import MIMETextfrom email.mime.multipart import MIMEMultipartfrom email.mime.image import MIMEImageos.chdir("C:\\Users\\h****m\\Desktop\\Auto_email")msgRoot = MIMEMultipart('related')if not isinstance(subject,unicode): #过滤或者不过滤貌似没啥影响 subject = unicode(subject, 'utf-8')msgRoot['Subject'] = subjectmsgRoot['From'] =fromaddrmsgRoot['To'] = ','.join(toaddrs)msgAlternative = MIMEMultipart('alternative')msgRoot.attach(msgAlternative)msg = """<p>Python 邮件发送测试...</p><p>图片演示：</p><p><img src="https:/article/cid:image1"></p>"""msgAlternative.attach(MIMEText(msg, 'html', 'utf-8'))fp = open('test.PNG', 'rb')msgImage = MIMEImage(fp.read())fp.close()# 定义图片 ID，在 HTML 文本中引用msgImage.add_header('Content-ID', '<image1>')msgRoot.attach(msgImage)s = smtplib.SMTP()s.connect(smtpaddr) #连接smtp服务器s.login(fromaddr,password) #登录邮箱s.sendmail(fromaddr, toaddrs, msgRoot.as_string()) #发送邮件s.quit()print "邮件发送成功！"#邮件发送成功！

对于case3，发送很不稳定，时而发送得出，时而报 SMTPDataError: 554错误，等有空了，看有没有方法弄个稳定的版本。case1,case2在工作中基本够用了。
