记录smtp错误的歌舞补丁
patch.singingdancing的Python项目详细描述
唱歌跳舞的简单而愚蠢的替代方法
如果引发了stmtp异常，进程队列将停止，但调度不会 请注意。
在 http://svn.plone.org/svn/collective/collective.singing/trunk/collective/singing/message.py try，catch在这种情况下不起作用，因为 我想是Zope.Sendmail吧。我认为 collective.dancing.composer.SMTPMailer.send必须有一个try ... except 那样的话。smtplib中的异常是：
“smtpexception”、“smtpserverdisconnected”、“smtpresponseexception”， “smtpsenderrefused”、“smtprecipientsrefused”、“smtpdataerror”， “smtpconnecterror”、“smtpheloerror”、“smtpauthenticationerror”，
SMTPRecipientsRefused和SMTPSenderRefused对于 调度过程，我认为它们可以在SMTPMailer中捕获。在我的 案例中，收件人收到了同一时事通讯的100封邮件，因为 空电子邮件地址的队列失败。队列永远不会被清除， @@dancing.utils/tick_and_dispatch通过阻塞zope服务器完成。

所以这个蛋的目的就是避免这个！！：
>>> from zope.component import getUtility >>> from zope.sendmail.mailer import ISMTPMailer >>> utility = getUtility(ISMTPMailer, name= 'patchplone.smtp') >>> utility <patch.singingdancing.composer.SMTPMailer...>
为smtplib提供一个简单的补丁：
>>> from zope.sendmail.mailer import SMTPMailer
>>> from smtplib import SMTPRecipientsRefused
>>> from smtplib import SMTPSenderRefused
>>> def new_send(self, from_addr, to_addrs, msg):
... if to_addrs == ['toto@host.com']:
... raise SMTPSenderRefused(500, 'failed',to_addrs)
... elif to_addrs == []:
... raise SMTPRecipientsRefused(to_addrs)
... else:
... return {}
>>> SMTPMailer.send = new_send
现在测试函数：
>>> utility.send('y.boussard@ingeniweb.com',['y.boussard@free.fr',],'')
{}
>>> utility.send('y.boussard@ingeniweb.com',['toto@host.com',],'')
{'toto@host.com':...}
>>> utility.send('y.boussard@ingeniweb.com',[],'')
{'y.boussard@ingeniweb.com':...}
