关于TRAC不能发mail的解释

首先在trac.ini文件中配置一下mail选项和日志选项。使日志文件记录可以开启。通过查看日志。看到以下问题
raceback (most recent call last):
  File "C:\Python24\Lib\site-packages\trac\ticket\web_ui.py", line 562, in _do_save
    tn.notify(ticket, newticket=False, modtime=now)
  File "C:\Python24\Lib\site-packages\trac\ticket\notification.py", line 129, in notify
    NotifyEmail.notify(self, ticket.id, subject)
  File "C:\Python24\Lib\site-packages\trac\notification.py", line 216, in notify
    Notify.notify(self, resid)
  File "C:\Python24\Lib\site-packages\trac\notification.py", line 114, in notify
    self.begin_send()
  File "C:\Python24\Lib\site-packages\trac\notification.py", line 287, in begin_send
    self.server.login(self.user_name, self.password)
  File "C:\Python24\lib\smtplib.py", line 591, in login
    raise SMTPAuthenticationError(code, resp)
SMTPAuthenticationError: (334, 'UGFzc3dvcmQ6')

其他的提示也差不多是这一种了
其实上述只是提供了一个程序调用的过程。在调用smtplib。py这个模块的时候出了问题
通过抓包显示（EHLO WINEYWFBF1TTDV 250-AUTH=LOGIN 250 AUTH LOGIN）。邮件服务器返回的是 auth=LOGIN，多了一个'='，所以我就在smtplib.py文件中的第569行加了这一段
if '='+method in authlist:
                    authmethod = method
                    break
以下程序（580行以下）
        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=""))
        elif authmethod is None:
            raise SMTPException("No suitable authentication method found.")
        if code not in [235, 503]:

修改为

        elif authmethod == AUTH_LOGIN:
            # Three stage: 1. sent "AUTH LOGIN"; 2. sent "user name"; 3. sent "password".
            # origial code combine stage 1 & 2 as below line:
            #(code, resp) = self.docmd("AUTH","%s %s" % (AUTH_LOGIN, encode_base64(user, eol="")))

            (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=""))
        elif authmethod is None:
            raise SMTPException("No suitable authentication method found.")
        if code not in [235, 503]:

 

 

保存后就肯定可以发邮件了啊。不知道最新版本是否解决了这个问题。大家可以测试一下啊！
