Create an online calendar by inviting this application to your events:

1. Invite the mailbox calendar to your events, replacing "test" with a name of your liking: my.mailbox.calendar+test@gmail.com.
2. View that the event is actually being processed. Here, also replace "test" with the name you chose before:
   https://my-mailbox-calendar.herokuapp.com/test.html
3. Subscribe to the calendar with any application using ICS.
   https://my-mailbox-calendar.herokuapp.com/test.ics

You can deploy the app using Heroku. There is a free plan.

This service uses an IMAP connection to the mailbox. When a request is made, the emails are filtered for the name of the calendar and are downloaded. Each event e-mail is processed for ICAL-entries.

Tested with:

• Thunderbird
• Lotus Notes

If you like to have it tested with other applications,

1. Create an event and invite my.mailbox.calendar+APPLICATION@gmail.com
2. Edit this event and send the changes - see if it changed.
3. Create a new event and delete it - see if it disappeares.
4. Open an issue for this application and mention the events you created.
5. In a pull request, add the sent/received emails and add them to the tests.
