python 接收邮件示例：pop3与imap

江湖浪人

首先是pop3与imap的区别：

简单来说主要区别就是imap可以不用把所有的邮件全部下载，就通过客户端直接对服务器上的邮件进行操作。IMAP它只下载邮件的主题，并不是把所有的邮件内容都下载下来.
=============================pop3=================================

import poplib  
emailServer = poplib.POP3('192.168.88.7')  
emailServer.user('qa01@corp.globalmarket.com')  
emailServer.pass_('123456')  
# 获取一些统计信息  
emailMsgNum, emailSize = emailServer.stat()  
print 'email number is %d and size is %d'%(emailMsgNum, emailSize)  
# 遍历邮件，并打印出每封邮件的标题  
for i in range(emailMsgNum):  
for piece in emailServer.retr(i+1)[1]:  
if piece.startswith('Subject'):  
print '\t' + piece  
break  
emailServer.quit()


=============================imap=================================

import imaplib, string, email
M = imaplib.IMAP4_SSL("imap.gmail.com")
print M
try:
try:
M.login('chemboking@gmail.com','12345678')
except Exception,e:
print 'login error: %s' % e
M.close()
M.select()
result, message = M.select()
typ, data = M.search(None, 'ALL')
for num in string.split(data[0]):
try:
typ, data = M.fetch(num, '(RFC822)')
msg = email.message_from_string(data[0][1])
print msg["From"]
print msg["Subject"]
print msg["Date"]
print "_______________________________"
except Exception,e:
print 'got msg error: %s' % e            
M.logout()
M.close()
except Exception, e:
print 'imap error: %s' % e
M.close()
