            try:
            if not self.check_smtp_connected("main", self.sender_addr):
                self.close("main", self.sender_addr)
                if not self.connect("main", self.sender_addr):
                    self.last_error = "req_id:%d,connect to %s main failed" % (mail_id, self.name)
                    raise Exception("req_id:%d,connect to %s main failed" % (mail_id, self.name))
            sender_addr = parseaddr(self.msg['From'])[1]
            recv_addr   = parseaddr(self.msg['To'])[1]
            self.smtp_conns[self.sender_addr].sendmail(self.msg['From'], self.msg['To'], self.msg.as_string())
        except Exception as e:
            glogger.warning("req_id:%d,send mail by %s failed, error: %s" % (mail_id, self.name, str(e)))
        else:
            sent_succ = True
            break

check_smtp_connected use noop()[0] to check connection to smtp server.

the first time I get : req_id:7066283,send mail by tx_smtp failed, error: timed out

so the exception is time out and then I use check_smtp_connected to check the connection, it's broken.

the second time I get: req_id:7066283,send mail by tx_smtp failed, error: (250, 'Ok') so the exception is (250, 'Ok')

I read source code of sendmail, but can't find the branch that will raise this exception.

so I'm heavily puzzled. and the result is my mailbox get two mail

    Please post some code that can fully demonstrate the problem and write a proper error description with the full traceback. – Klaus D. Nov 07 '17 at 09:28

I solve this problem,because I set the smtplib argument 'timeout=3'，and the mail is too big, so the first time I get "timed out". I guess the second time I get the reply of the first time,because I really get this mail twice ,but not proved. and I set timeout larger,and everything goes okay!
