我对编程很陌生，所以我在这里寻求帮助。我有一个包含超过 20 万封电子邮件的电子邮件文件夹。我试图将它们全部删除，因为它们让我慢了下来。我使用 IMAPClient 在 Python 3.7.2 中编写了一个脚本来尝试将它们全部删除，但我一直收到错误消息。

我试图删除文件夹中的所有电子邮件，并且我试图删除一天的价值。平均一天有大约 2k 封电子邮件。同时使用 'ALL' 和 'ON DD-MMM-YYYY"

import imapclient
imapObj = imapclient.IMAPClient('imap.server.com', ssl=True)
imapObj.login('email', 'password')

import pprint
pprint.pprint(imapObj.list_folders())

[((b'\\NoInferiors',), b'/', 'INBOX'),
 ((b'\\HasNoChildren',), b'/', 'Folder I want to delete'),
--all folders--

imapObj.select_folder('Folder I want to delete', readonly=False)
{b'PERMANENTFLAGS': (b'\\Answered', b'\\Flagged', b'\\Draft',         
b'\\Deleted', b'\\Seen', b'$Forwarded', b'$NotJunk', b'NotJunk', 
b'$MailFlagBit1', b'$MailFlagBit0', b'$MailFlagBit2', b'\\*'), 
b'FLAGS': (b'\\Answered', b'\\Flagged', b'\\Draft', b'\\Deleted', 
b'\\Seen', b'$Forwarded', b'$NotJunk', b'NotJunk', b'$MailFlagBit1', 
b'$MailFlagBit0', b'$MailFlagBit2'), b'EXISTS': 3792507, b'RECENT': 
0, b'UNSEEN': [b'3792504'], b'UIDVALIDITY': 1398179813, b'UIDNEXT': 
7577201, b'READ-WRITE': True}

UIDs = imapObj.search('ALL')
imapObj.delete_messages(UIDs)
Traceback (most recent call last):
  File "<pyshell#2>", line 1, in <module>
    imapObj.delete_messages(UIDs)

   typ, dat = self._simple_command(name, command, *args)

  File "/Library/Frameworks/Python.framework/Versions/3.7/lib/python3.7/imaplib

   raise self.error('%s command error: %s %s' % (name, typ, data))
imaplib.IMAP4.error: UID command error: BAD [b'Command line too large']

我希望电子邮件被删除，但命令只是错误地出现在上面。

UId 列表很长，无法发出一个请求，我们需要拆分每个删除。

UIDs = imapObj.search('ALL')
for UID in UIDs
    imapObj.delete_messages([UID])
    print( 'Deleted--->'+str(UID))
