問題：
直接配置logging發(fā)送smtp協(xié)議465端口發(fā)送郵件會(huì)出現(xiàn)页眯，如下錯(cuò)誤，如圖：

其實(shí)原因就是厢呵，發(fā)送郵件時(shí)直接調(diào)用smtplib中的SMTP方法窝撵，該方法是沒有封裝支持TLS協(xié)議，所以會(huì)出現(xiàn)超時(shí)連接錯(cuò)誤襟铭。

解決方法：
重寫發(fā)送郵件的emit方法
修改前：

    def emit(self, record):
        """
        Emit a record.

        Format the record and send it to the specified addressees.
        """
        try:
            import smtplib
            from email.message import EmailMessage
            import email.utils

            port = self.mailport
            if not port:
                port = smtplib.SMTP_PORT
            smtp = smtplib.SMTP(self.mailhost, port, timeout=self.timeout)
            msg = EmailMessage()
            msg['From'] = self.fromaddr
            msg['To'] = ','.join(self.toaddrs)
            msg['Subject'] = self.getSubject(record)
            msg['Date'] = email.utils.localtime()
            msg.set_content(self.format(record))
            if self.username:
                if self.secure is not None:
                    smtp.ehlo()
                    smtp.starttls(*self.secure)
                    smtp.ehlo()
                smtp.login(self.username, self.password)
            smtp.send_message(msg)
            smtp.quit()
        except Exception:
            self.handleError(record)

修改后：

def emit(self, record):
    """
    Overwrite the logging.handlers.SMTPHandler.emit function with SMTP_SSL.
    Emit a record.
    Format the record and send it to the specified addressees.
    """
    try:
        import smtplib
        from email.utils import formatdate
        port = self.mailport
        if not port:
            port = smtplib.SMTP_PORT
        smtp = smtplib.SMTP_SSL(self.mailhost, port, timeout=5)
        msg = self.format(record)
        msg = "From: %s\r\nTo: %s\r\nSubject: %s\r\nDate: %s\r\n\r\n%s" % (
        self.fromaddr, ", ".join(self.toaddrs), self.getSubject(record), formatdate(), msg)
        if self.username:
            smtp.ehlo()
            smtp.login(self.username, self.password)
        smtp.sendmail(self.fromaddr, self.toaddrs, msg)
        smtp.quit()
    except (KeyboardInterrupt, SystemExit):
        raise
    except:
        self.handleError(record)

修改完之后碌奉，直接把原來的方法覆蓋就好了，代碼如下：

handlers.SMTPHandler.emit = emit  # 需要導(dǎo)入from logging import handlers模塊

最后問題就解決啦寒砖，可以直接發(fā)送TLS協(xié)議的郵件赐劣。
