查找自上次使用python imaplib2检查以来添加到imap邮箱的新邮件? [英] Find new messages added to an imap mailbox since I last checked with python imaplib2?

问题描述

我正在尝试编写一个程序，该程序监视IMAP邮箱并将每条新收到的邮件自动复制到存档"文件夹中.我正在使用实现IDLE命令的imaplib2.这是我的基本程序:

I am trying to write a program that monitors an IMAP mailbox and automatically copies every new incoming message into an "Archive" folder. I'm using imaplib2 which implements the IDLE command. Here's my basic program:

M = imaplib2.IMAP4("mail.me.com")
M.login(username,password)
lst = M.list()
assert lst[0]=='OK'
for mbx in lst[1]:
    print "Mailboxes:",mbx

def process(m):
    print "m=",m
    res = M.recent()
    print res


M.select('INBOX')
M.examine(mailbox='INBOX',callback=process)
while True:
    print "Calling idle..."
    M.idle()
    print "back from idle"
M.close()
M.logout()

当邮箱发生第一次更改时，它将正确打印邮箱并运行process().但是last()的响应对我来说是没有意义的，并且在收到第一条消息后，我再也没有收到任何其他通知.

It prints the mailboxes properly and runs process() when the first change happens to the mailbox. But the response from recent() doesn't make sense to me, and after the first message I never get any other notifications.

有人知道该怎么做吗?

推荐答案

请参见

See example and references in python-imap-idle-with-imaplib2. The module involves threading, you should pay attention to event synchronization.

该示例建议与事件进行同步，并将邮件处理留给阅读器:

The example suggests synchronizing with events, and leaves mail processing to the reader:

# The method that gets called when a new email arrives. 
# Replace it with something better.
def dosync(self):
    print "Got an event!"

从问题中暗示，更好" 可以是:

Taking a hint from the question, "something better" can be:

# Replaced with something better.
def dosync(self):
    print "Got an event!"
    res = self.M.recent()
    print res
