Python实例讲解 -- 接收邮件 (亲测)
1. 主要使用了 poplib 组件

    # -*- coding: utf-8 -*-            import poplib      from email import parser            host = 'pop.gmail.com'      username = 'mine@gmail.com'      password = '*******'            pop_conn = poplib.POP3_SSL(host)      pop_conn.user(username)      pop_conn.pass_(password)            #Get messages from server:      messages = [pop_conn.retr(i) for i in range(1, len(pop_conn.list()[1]) + 1)]            # Concat message pieces:      messages = ["\n".join(mssg[1]) for mssg in messages]            #Parse message intom an email object:      messages = [parser.Parser().parsestr(mssg) for mssg in messages]      for message in messages:          print message['Subject']      pop_conn.quit()  

优点： 可以输出内容
缺点： 只检测一次

2. 使用第三方插件 chilkat

# -*- coding: utf-8 -*-    import sys  import chilkat    host = 'pop.gmail.com'  username = 'mine@gmail.com'  password = '******'    # The mailman object is used for receiving (POP3)  # and sending (SMTP) email.  mailman = chilkat.CkMailMan()    # Any string argument automatically begins the 30-day trial.  success = mailman.UnlockComponent("30-day trial")  if (success != True):      print "Component unlock failed"      sys.exit()    # Set the GMail account POP3 properties.  mailman.put_MailHost(host)  mailman.put_PopUsername(username)  mailman.put_PopPassword(password)  mailman.put_PopSsl(True)  mailman.put_MailPort(995)    # Read mail headers and one line of the body.  # To get the full emails, call CopyMail instead (no arguments)  bundle = mailman.GetAllHeaders(1)    if (bundle == None ):      print mailman.lastErrorText()      sys.exit()    for i in range(0,bundle.get_MessageCount()):      email = bundle.GetEmail(i)        # Display the From email address and the subject.      print email.ck_from()      print email.subject() + "\n" 

安装见附件

安装：http://www.chilkatsoft.com/installPython27.asp

安装很简单，点击 showPythonPath.bat 测试一下环境，然后复制 _chilkat.pyd 和 chilkat.py 到 Python27\Lib\site-packages\ 下就可以

优点： 可以多次检测

缺点： 只可以看到来源和主题，无法看到内容

3. 检测邮件，返回未读数值

    def gmail_checker(username,password):              import imaplib,re              i=imaplib.IMAP4_SSL('pop.gmail.com')              try:                      i.login(username,password)                      x,y=i.status('INBOX','(MESSAGES UNSEEN)')                      messages=int(re.search('MESSAGES\s+(\d+)',y[0]).group(1))                      unseen=int(re.search('UNSEEN\s+(\d+)',y[0]).group(1))                      return (messages,unseen)              except:                      return False,0            # Use in your scripts as follows:            messages,unseen = gmail_checker('mine@gmail.com','******')      print "%i messages, %i unseen" % (messages,unseen)  

4. 很好的返回主题和内容

    import imaplib      import email            def extract_body(payload):          if isinstance(payload,str):              return payload          else:              return '\n'.join([extract_body(part.get_payload()) for part in payload])            conn = imaplib.IMAP4_SSL("pop.gmail.com", 993)      conn.login("mine@gmail.com", "******")      conn.select()      typ, data = conn.search(None, 'UNSEEN')      try:          for num in data[0].split():              typ, msg_data = conn.fetch(num, '(RFC822)')              for response_part in msg_data:                  if isinstance(response_part, tuple):                      msg = email.message_from_string(response_part[1])                      subject=msg['subject']                                         print(subject)                      payload=msg.get_payload()                      body=extract_body(payload)                      print(body)              typ, response = conn.store(num, '+FLAGS', r'(\Seen)')      finally:          try:              conn.close()          except:              pass          conn.logout()
