电子邮件阅读代码在公司系统中无效

Question

我使用此代码从邮件服务器检索电子邮件：

import email
import imaplib
from bs4 import BeautifulSoup

user='[email protected]'
password='PASSWORD'
mail = imaplib.IMAP4_SSL('SERVER_NAME',PORT)
mail.login(user,password)

mail.select('inbox')
result,data=mail.uid('search',None,'(HEADER Subject "Reply Of Confirmation") UNSEEN')
inbox_item_list=data[0].split()
res=None
for num in inbox_item_list:
      result1,email_data=mail.uid('fetch',num,'RFC822')
      #print(email_data)
      email_message = email.message_from_string(email_data[0][1].decode("utf-8"))
      #print(dir(email_message))
      if email_message.is_multipart():
          for payload in email_message.get_payload():
              if payload.get_content_maintype() == 'text':
                  soup = BeautifulSoup(payload.get_payload(),"html.parser")
                  text = soup.get_text()
                  res=text
                  break
      else:
          soup = BeautifulSoup(payload.get_payload())
          text = soup.get_text()
          res=text
          break
print("Content-type:text/html\r\n\r\n")
print(res)

此代码在我的个人笔记本电脑上成功运行，但在公司系统上运行时出现此错误：

 sock.connect(sa)
ConnectionRefusedError: [WinError 10061] No connection could be made because the target machine actively refused it

我该如何解决？

这是完整的错误追溯：

imaplib.IMAP4_SSL('imap-eu.dc.ege.ds',993)尝试连接到DNS中不存在的主机。
