Прошу прощения.
Начал писать скрипт и не могу понять как обработать исключение при таймауте от SMTP-сервера.

try:		
        email_logger.info("INS" + time.strftime("%d-%m-%Y",time.localtime(os.path.getmtime(file))))
except TimeoutError:
	logging.warning("Warning! SMTP server - TimeOut!")

При ошибке всё равно выплёвывает всё в консоль.

Traceback (most recent call last):
  File "C:\Python27\lib\logging\handlers.py", line 929, in emit
    smtp = smtplib.SMTP(self.mailhost, port, timeout=self._timeout)
  File "C:\Python27\lib\smtplib.py", line 256, in __init__
    (code, msg) = self.connect(host, port)
  File "C:\Python27\lib\smtplib.py", line 316, in connect
    self.sock = self._get_socket(host, port, self.timeout)
  File "C:\Python27\lib\smtplib.py", line 291, in _get_socket
    return socket.create_connection((host, port), timeout)
  File "C:\Python27\lib\socket.py", line 571, in create_connection
    raise err
timeout: timed out

Само подключение выглядит так:

handler = handlers.SMTPHandler(('192.168.1.2', 25), FROM, TO, SUBJECT)
email_logger = logging.getLogger('~@~.ru')
email_logger.addHandler(handler)
email_logger.setLevel = logging.info

а там сказано

timeout

except socket.timeout:

except socket.error:

всё равно ошибку вываливают.

всё равно ошибку вываливают.

какую ошибку? покажите код
и почему вы думаете что оишбка должна быть в

email_logger.info("INS" + time.strftime("%d-%m-%Y",time.localtime(os.path.getmtime(file))))

Извиняюсь за import ибо вырывал кусок из большого файла с кучей модулей.

handler = handlers.SMTPHandler(('192.168.1.5', 25), FROM, TO, SUBJECT)

На данный момент ip адрес из

handlers.SMTPHandler(('192.168.1.5', 25), FROM, TO, SUBJECT)

с моего рабочего места не доступен. В др. сети он полностью рабочий, но хочется прописать обработку исключения, что бы не было неприятных сюрпризов.

Как я понял, проблема из-за handlers.SMTPHandler, ибо на остальные ошибки исключения работают.
