我試圖使用Python成功驗證Exchange SMTP網關。嘗試從Python和NTLM庫發送電子郵件時出現錯誤535
我使用的是https://github.com/jborean93/ntlm-auth和Python 3.5.2的ntlm_auth模塊。
- 我可以使用這些憑據登錄到webmail。我知道他們工作。
- 我可以使用PowerShell發送電子郵件，我知道這很有用。
這是我正在使用的代碼。我已閱讀NTLM規範，並且服務器不接受已認證的消息。 5.7.3是一個通用錯誤，是否有更好的方法來處理這種情況？
from smtplib import SMTP
from ntlm_auth.ntlm import Ntlm
import socket
from smtplib import SMTPException, SMTPAuthenticationError
workstation = socket.gethostname().upper()
def ntlm_authenticate(smtp, domain, username, password):
code, response = smtp.docmd("AUTH", "NTLM")
ntlm_context = Ntlm(ntlm_compatibility=2)
if code != 334:
raise SMTPException("Server did not respond as expected to NTLM negotiate message")
code, response = smtp.docmd(ntlm_context.create_negotiate_message(domain, workstation).decode())
if code != 334:
raise SMTPException("Server did not respond as expected to NTLM challenge message")
ntlm_context.parse_challenge_message(response)
code, response = smtp.docmd(ntlm_context.create_authenticate_message(username, password,
domain, workstation).decode())
if code != 235:
raise SMTPAuthenticationError(code, response)
EXCHANGE_PASSWORD = 'ThisIsReallyMyPassword!'
fromaddr = '[email protected]'
toaddrs = '[email protected]'
msg= 'hello world!'
print("Message length is", len(msg))
conn = SMTP('webmail.ourcompany.com')
conn.set_debuglevel(1)
conn.starttls()
conn.ehlo()
ntlm_authenticate(conn, 'DOMAINXXX', 'anthony.shaw', EXCHANGE_PASSWORD)
conn.sendmail(fromaddr, toaddrs, msg)
conn.quit()
這裏是會話的痕跡，各種加密的話錯位安全
