前段时间突然发现blog的post to qzone的插件不能使用了，返回的异常如下：  
  
File "C:/Python25/lib/smtplib.py", line 591, in login  
    raise SMTPAuthenticationError(code, resp)  
SMTPAuthenticationError: (334, 'UGFzc3dvcmQ6')  
  
通过抓包发现stmtp.qq.com  
  
connect: ('smtp.qq.com', 25)  
connect: ('58.251.150.237', 25)  
reply: '220 Esmtp QQ Mail Server/r/n'  
reply: retcode (220); Msg: Esmtp QQ Mail Server  
connect: Esmtp QQ Mail Server  
send: 'ehlo \[192.168.1.177\]/r/n'  
reply: '250-esmtp.qq.com/r/n'  
reply: '250-PIPELINING/r/n'  
reply: '250-SIZE 52428800/r/n'  
reply: '250-AUTH LOGIN/r/n'  
reply: '250-AUTH=LOGIN/r/n'  
reply: '250 8BITMIME/r/n'  
reply: retcode (250); Msg: esmtp.qq.com  
PIPELINING  
SIZE 52428800  
AUTH LOGIN  
AUTH=LOGIN  
8BITMIME  
send: 'AUTH LOGIN \*\*\*\*\*\*\*\*\*\*/r/n'  
reply: '334 VXNlcm5hbWU6/r/n'  
reply: retcode (334); Msg: VXNlcm5hbWU6  
send: '\*\*\*\*\*/r/n'  
reply: '334 UGFzc3dvcmQ6/r/n'  
reply: retcode (334); Msg: UGFzc3dvcmQ6  
  
发现邮件服务器返回的是 AUTH=LOGIN，多了一个'=',打开smtplib.py找到  
  
elif authmethod == AUTH\_LOGIN:  
    (code, resp) = self.docmd("AUTH",  
        "%s %s" % (AUTH\_LOGIN, encode\_base64(user, eol="")))  
    if code != 334:  
        raise SMTPAuthenticationError(code, resp)  
    (code, resp) = self.docmd(encode\_base64(password, eol=""))  
  
修改为：  
  
elif authmethod == AUTH\_LOGIN:  
    \# Three stage: 1. sent "AUTH LOGIN"; 2. sent "user name"; 3. sent "password".  
    (code, resp) = self.docmd("AUTH", AUTH\_LOGIN)  
    if code != 334:  
        raise SMTPAuthenticationError(code, resp)  
    (code, resp) = self.docmd(encode\_base64(user, eol=""))  
    if code != 334:  
        raise SMTPAuthenticationError(code, resp)  
    (code, resp) = self.docmd(encode\_base64(password, eol=""))  
  
找到  
  
if method in authlist:  
    authmethod = method  
    break  
  
修改为：  
  
if method in authlist or ('=%s' % method) in authlist:  
    authmethod = method  
    break  
  
最好是将此文件另存到你的项目文件里调用，这样就不需要换个环境就先要修改smtplib.py.
