仅从电子邮件中检索新消息

Question

我正在尝试使用 Imaplib 从电子邮件地址检索消息，到目前为止我已经能够检索消息，但是，我只对原始消息感兴趣，这意味着如果消息是“Re：”，那么我不'不想要以前的消息，我只想要新的消息，这可能吗？

这是我从 python 得到的：

test # 10\r\n\r\nOn Thu, Dec 1, 2011 at 11:17 PM, paulo alvarado\r\n<[email protected]>wrote:\r\n\r\n> test # 9\r\n>\r\n>\r\n> On Thu, Dec 1, 2011 at 11:15 PM, paulo alvarado <[email protected]\r\n> > wrote:\r\n>\r\n>> test # 8\r\n>>\r\n>>\r\n>> On Thu, Dec 1, 2011 at 11:14 PM, paulo alvarado <\r\n>> [email protected]> wrote:\r\n>>\r\n>>> test # 7\r\n>>>\r\n>>> On Thu, Dec 1, 2011 at 10:36 PM, paulo alvarado <\r\n>>> [email protected]> wrote:\r\n>>>\r\n>>>> test # 6\r\n>>>>\r\n>>>>\r\n>>>> On Thu, Dec 1, 2011 at 10:36 PM, paulo alvarado <\r\n>>>> [email protected]> wrote:\r\n>>>>\r\n>>>>> test # 5\r\n>>>>>\r\n>>>>>\r\n>>>>> On Thu, Dec 1, 2011 at 9:46 PM, paulo alvarado <\r\n>>>>> [email protected]> wrote:\r\n>>>>>\r\n>>>>>> this is test # 4\r\n>>>>>>\r\n>>>>>>\r\n>>>>>>\r\n>>>>>> On Thu, Dec 1, 2011 at 7:13 PM, paulo alvarado <\r\n>>>>>> [email protected]> wrote:\r\n>>>>>>\r\n>>>>>>> this is test # 1\r\n>>>>>>>\r\n>>>>>>\r\n>>>>>>\r\n>>>>>\r\n>>>>\r\n>>>\r\n>>\r\n>\r\n

正如你所看到的，测试 #10 是新消息，其他内容是之前的回复 我正在使用 python2.7

编辑

我有一个票证应用程序，所以基本上，我希望用户能够通过电子邮件提交票证，所以用户的电子邮件是作者，主题是标题，消息正文是描述，除了如何处理回复之外，我一切正常，因为此时，如果用户通过电子邮件回复，票证的描述将不仅包含新问题（或响应）但它也会包含以前的，所以我想知道是否有办法删除以前的回复并只保留新的回复，这是我的问题的图片。

import imaplib
conn = imaplib.IMAP4_SSL(host='mail.example.com')
# or conn =imaplib.IMAP4(host='mail.example.com') for no SSL 
try: 
    (retcode, capabilities) = conn.login('user', 'pass') 
except: 
    # cannot login
conn.select(readonly=1) # Select inbox or default namespace 
(retcode, messages) = conn.search(None, '(UNSEEN)') 
if retcode == 'OK': 
    for message in messages[0].split(' '): 
        print 'Processing :', message 
        (ret, mesginfo) = conn.fetch(message, '(BODY[HEADER.FIELDS (SUBJECT FROM)])') 
        if ret == 'OK': 
            # process message here 
conn.close() 

conn.search(None, '(UNSEEN)') 是代码中的重要部分。
