This plugin is very handy when you are using the Booking Calendar and want to insert bookings from other parties like airbnb. But there is a big mishap in the code: it automatically appoints “ics@<www.yourwebsite.com>” as the bookers e-mail. This is a non-existing email address! If you have the Booking Calendar set on automatical mailing when you change/update a booking, you can imagine was happens; the plugin starts mailing to non-existing e-mail addresses, resulting in hundreds of bounces a day!
