如何在python中设置到本地hmail服务器的连接？

如何解决如何在python中设置到本地hmail服务器的连接？

我已经在我的本地机器上设置了一个 hmailserver。我也在使用一个 python 脚本来读取电子邮件。当我连接到 Outlook 时，python 脚本运行良好。但是我的 hmailserver 的本地连接有问题。我希望脚本连接到我的本地电子邮件服务器 (hmailserver) 并从那里读取电子邮件。我很难建立这个连接，而且我找不到与 hmailserver 和 python 相关的好的文档。

import email
import imaplib

EMAIL = '[e-mail]'
PASSWORD = 'test123'
SERVER = '0.0.0.0/143'#'smtp-mail.outlook.com'

# connect to the server and go to its inBox
mail = imaplib.IMAP4_SSL(SERVER)
mail.login(EMAIL,PASSWORD)
# we choose the inBox but you can select others
mail.select('inBox')

# we'll search using the ALL criteria to retrieve
# every message inside the inBox
# it will return with its status and a list of ids
status,data = mail.search(None,'ALL')
# the list returned is a list of bytes separated
# by white spaces on this format: [b'1 2 3',b'4 5 6']
# so,to separate it first we create an empty list
mail_ids = []
# then we go through the list splitting its blocks
# of bytes and appending to the mail_ids list
for block in data:
    # the split function called without parameter
    # transforms the text or bytes into a list using
    # as separator the white spaces:
    # b'1 2 3'.split() => [b'1',b'2',b'3']
    mail_ids += block.split()

# Now for every id we'll fetch the email
# to extract its content
for i in mail_ids:
    # the fetch function fetch the email given its id
    # and format that you want the message to be
    status,data = mail.fetch(i,'(RFC822)')

    # the content data at the '(RFC822)' format comes on
    # a list with a tuple with header,content,and the closing
    # byte b')'
    for response_part in data:
        # so if its a tuple...
        if isinstance(response_part,tuple):
            # we go for the content at its second element
            # skipping the header at the first and the closing
            # at the third
            message = email.message_from_bytes(response_part[1])

            # with the content we can extract the info about
            # who sent the message and its subject
            mail_from = message['from']
            mail_subject = message['subject']

            # then for the text we have a little more work to do
            # because it can be in plain text or multipart
            # if its not plain text we need to separate the message
            # from its annexes to get the text
            if message.is_multipart():
                mail_content = ''

                # on multipart we have the text message and
                # another things like annex,and html version
                # of the message,in that case we loop through
                # the email payload
                for part in message.get_payload():
                    # if the content type is text/plain
                    # we extract it
                    if part.get_content_type() == 'text/plain':
                        mail_content += part.get_payload()
            else:
                # if the message isn't multipart,just extract it
                mail_content = message.get_payload()

            # and then let's show its result
            print(f'From: {mail_from}')
            print(f'Subject: {mail_subject}')
            print(f'Content: {mail_content}')

上面是我正在使用的代码，连接到我的 Outlook 电子邮件工作正常（smtp-mail.outlook.com）。但是当我替换服务器连接到我的本地主机（端口 143 上的 0.0.0.0）时，我收到以下错误

File "c:/Users/yehya/Desktop/relay.py",line 10,in <module>
    mail = imaplib.IMAP4_SSL(SERVER)
  File "C:\Users\yehya\AppData\Local\Programs\Python\python38\lib\imaplib.py",line 1297,in __init__
    IMAP4.__init__(self,host,port)
  File "C:\Users\yehya\AppData\Local\Programs\Python\python38\lib\imaplib.py",line 198,in __init__
    self.open(host,line 1310,in open
    IMAP4.open(self,line 303,in open
    self.sock = self._create_socket()
  File "C:\Users\yehya\AppData\Local\Programs\Python\python38\lib\imaplib.py",line 1300,in _create_socket
    sock = IMAP4._create_socket(self)
  File "C:\Users\yehya\AppData\Local\Programs\Python\python38\lib\imaplib.py",line 293,in _create_socket
    return socket.create_connection((host,self.port))
  File "C:\Users\yehya\AppData\Local\Programs\Python\python38\lib\socket.py",line 787,in create_connection
    for res in getaddrinfo(host,port,SOCK_STREAM):
  File "C:\Users\yehya\AppData\Local\Programs\Python\python38\lib\socket.py",line 918,in getaddrinfo
    for res in _socket.getaddrinfo(host,family,type,proto,flags):
socket.gaierror: [Errno 11001] getaddrinfo Failed

感谢任何帮助，谢谢

解决方法

问题在于 IP 地址 0.0.0.0。这是一个“监听”地址，而不是 localhost 地址。参见the wikipedia entry。

如果要环回同一台机器，则需要使用 IP 地址 127.0.0.1。对应的 wikipedia article。

我也认为服务器地址中的 / 可能不正确。我认为您需要将其替换为 : 以指定端口。

换行：

SERVER = '0.0.0.0/143'#'smtp-mail.outlook.com'

到下面一个：

SERVER = '127.0.0.1:143'#'smtp-mail.outlook.com'

,

max 的评论是正确的。正确的格式是 mail = imaplib.IMAP4_SSL(SERVER,143)。在我的情况下，服务器也不需要 ssl 方法。所以mail=imaplib.IMAP4(SERVER,143)
