Check my emails and send them to Slack!
Super simple and made in a couple of hours, so don't expect much (duplicated code, configuration isn't centralized, security is a mess, plaintext passwords lol).
First, add your mail providers' data to the config_init.py file.
To configure the bot itself, modify slack_bot.py with yout Slack token and the Slack channel where you want to receive the notifications.
Once that's done run on your virtualenv:
pip install -r requirements.txt
python config_init.py
python slack_bot.py
And you'll be notified about new emails every 5 minutes!
