IMAP - 如何删除邮件

28

我该如何从邮箱中删除邮件?我正在使用这段代码,但是信件并没有被删除。抱歉我的英语不好。

def getimap(self,server,port,login,password):
    import imaplib, email
    box = imaplib.IMAP4(server,port)
    box.login(login,password)
    box.select()
    box.expunge()
    typ, data = box.search(None, 'ALL')
    for num in data[0].split() :
        typ, data = box.fetch(num, '(UID BODY[TEXT])')
        print num
        print data[0][1]
    box.close()
    box.logout()

这是删除收件箱中所有电子邮件的工作代码:

import imaplib
box = imaplib.IMAP4_SSL('imap.mail.microsoftonline.com', 993)
box.login("user@domain.com","paswword")
box.select('Inbox')
typ, data = box.search(None, 'ALL')
for num in data[0].split():
   box.store(num, '+FLAGS', '\\Deleted')
box.expunge()
box.close()
box.logout()

我认为你应该首先将要删除的电子邮件进行标记。例如:

for num in data[0].split():
   box.store(num, '+FLAGS', '\\Deleted')
box.expunge()

以下是我的做法,非常快速,因为我不会逐一删除每封电子邮件(存储)而是传递列表索引。这适用于个人和企业的Gmail(Google应用程序商店)。首先选择要使用的文件夹/标签,m.list()将显示所有可用的文件夹/标签。然后搜索超过一年的电子邮件,并将其移到垃圾桶中。然后将垃圾桶中的所有电子邮件标记为删除标志并清除所有内容:

#!/bin/python

import datetime
import imaplib

m = imaplib.IMAP4_SSL("imap.gmail.com")  # server to connect to
print "Connecting to mailbox..."
m.login('gmail@your_gmail.com', 'your_password')

print m.select('[Gmail]/All Mail')  # required to perform search, m.list() for all lables, '[Gmail]/Sent Mail'
before_date = (datetime.date.today() - datetime.timedelta(365)).strftime("%d-%b-%Y")  # date string, 04-Jan-2013
typ, data = m.search(None, '(BEFORE {0})'.format(before_date))  # search pointer for msgs before before_date

if data != ['']:  # if not empty list means messages exist
    no_msgs = data[0].split()[-1]  # last msg id in the list
    print "To be removed:\t", no_msgs, "messages found with date before", before_date
    m.store("1:{0}".format(no_msgs), '+X-GM-LABELS', '\\Trash')  # move to trash
    print "Deleted {0} messages. Closing connection & logging out.".format(no_msgs)
else:
    print "Nothing to remove."

#This block empties trash, remove if you want to keep, Gmail auto purges trash after 30 days.
print("Emptying Trash & Expunge...")
m.select('[Gmail]/Trash')  # select all trash
m.store("1:*", '+FLAGS', '\\Deleted')  #Flag all Trash as Deleted
m.expunge()  # not need if auto-expunge enabled

print("Done. Closing connection & logging out.")
m.close()
m.logout()
print "All Done."

我为你点赞批量删除(如果想要删除整个邮箱,这确实更快)。 - Yaroslav Nikitenko

以下代码将打印一些消息头字段,然后删除消息。
import imaplib
from email.parser import HeaderParser
m = imaplib.IMAP4_SSL("your_imap_server")
m.login("your_username","your_password")
# get list of mailboxes
list = m.list()
# select which mail box to process
m.select("Inbox") 
resp, data = m.uid('search',None, "ALL") # search and return Uids
uids = data[0].split()    
mailparser = HeaderParser()
for uid in uids:
    resp,data = m.uid('fetch',uid,"(BODY[HEADER])")        
    msg = mailparser.parsestr(data[0][1])       
    print (msg['From'],msg['Date'],msg['Subject'])        
    print m.uid('STORE',uid, '+FLAGS', '(\\Deleted)')
print m.expunge()
m.close() # close the mailbox
m.logout() # logout

如果您正在使用GMail,操作略有不同:
  1. 将其移至[Gmail]/垃圾文件夹中。
  2. 从[Gmail]/垃圾文件夹中删除它(添加\删除标记)
所有位于[Gmail]/垃圾邮件和[Gmail]/垃圾文件夹中的电子邮件在30天后都将被删除。如果您从[Gmail]/垃圾邮件或[Gmail]/垃圾文件夹中删除消息,则该消息将被永久删除。
请记得在设置已删除标记后调用EXPUNGE。

根据日期条件删除所有电子邮件。 该程序将删除当前日期之前20天的所有电子邮件。 在程序中调整变量Dy中的天数。例如,DY = 20。

这是我在Outlook收件箱文件夹中使用的流程,用于删除或保留电子邮件。 管理电子邮件是一个持续的维护问题。 有时我有成千上万封需要删除的邮件。 我创建了两个Python程序,可以使我有效地管理这个流程。

首先,我编写一个Python程序来创建文本和CSV文件。 文本和CSV文件包含两部分。

  1. 每个唯一电子邮件的计数。
  2. 唯一发件人电子邮件地址。

其次,我编辑文本或CSV文件以创建两个文本文件。

  1. EmailsToKeep.txt。 A. 我想保留的电子邮件没有删除条件。 B. 我将手动管理这些电子邮件。
  2. EmailsToKeepForAtLeast30Days.txt。 A. 基于变量EndDy的日期值,我希望保留或删除的电子邮件。 我将根据需要附加这两个文本文件。

第三,我编写第二个Python程序,根据四个条件删除或保留电子邮件。

  1. Delete emails that have no email address.

  2. Keep emails that are in the EmailsToKeep.txt text file.

  3. Keep or delete emails that are in the EmailsToKeepForAtLeast30Days.txt text file. A. Keep emails if date is newer than the date value of variable EndDy. B. Delete emails if date is older than the date value of variable EndDy.

  4. Delete emails that were not included in any of the EmailsToKeep.txt or EmailsToKeepForAtLeast30Days.txt text files. Video link: https://youtu.be/bTgb3tO5r-8

     First python program.

尝试使用https://github.com/ikvk/imap_tools

from imap_tools import MailBox 

# DELETE all messages from INBOX
with MailBox('imap.mail.com').login('test@mail.com', 'password', 'INBOX') as mailbox:
    mailbox.delete(mailbox.uids('ALL'))

This Python 3 program will scan an email account using IMAP for messages older than
a certain age and delete them.

Old email can be deleted from all folders or each folder.

Because of the length of time bulikng deleting takes, folders can be scanned first
then the deletions can be left running (which might take several hours for many
thousands of messages.)

After running this, you may need to "empty" your deleted items/Trash folder to recover the space.
With hotmail/live/outlook accounts (i.e. online Microsoft ones) you will need to manually empty "recoverable items" too.
This is done within the "deleted items" folder when viewing your webmail.

#You can hardcode your IMAP settings here, or they can be entered interactively.
#If "user" is set to a non-empty value, it is assumed the other values are set
