How to Send Python Logs via Email with SMTPHandler (Fix QQ Timeout)

Earlier someone asked in a group about configuring Python to send log emails; I found it insightful, so I'm documenting it here to avoid pitfalls later.

We can use Python's logging.handlers.SMTPHandler to send logs to a specified mailbox. It works smoothly with 163.com mail settings, but using QQ enterprise mail repeatedly caused a login timeout error.

By examining the logging source code, we discovered that the default logging handlers use TLS connections, while QQ enterprise mail and Gmail require SSL connections, leading to the failure.

Finally, a simple configuration is provided.

# logging.conf complete configuration
[loggers]
keys=root,test

[handlers]
keys=consoleHandler,fileHandler,testHandler

[formatters]
keys=simpleFormatter

[formatter_simpleFormatter]
format=%(asctime)s - %(name)s - %(levelname)s - %(message)s - [%(filename)s:%(lineno)s]
datefmt=

[logger_root]
level=INFO
handlers=consoleHandler,fileHandler

[logger_test]
level=INFO
handlers=testHandler
qualname=test
propagate=0

[handler_consoleHandler]
class=StreamHandler
level=INFO
formatter=simpleFormatter
args=(sys.stdout,)

[handler_fileHandler]
class=FileHandler
level=INFO
formatter=simpleFormatter
args=('log/spider_db.log', 'a')

[handler_testHandler]
class=handlers.SMTPHandler
level=INFO
formatter=simpleFormatter
args=(('smtp.163.com',25), '[email protected]', ['[email protected]','[email protected]'], 'Test SMTPHandler', ('username', 'password'))

# Email test example
import logging
import logging.config
logging.config.fileConfig("logging.conf")
logger = logging.getLogger('test')
logger.info('hello body ~')
