I have just recently tried to get this plugin to work in my setup.
The strange thing is that I fail to send emails from ical. When the event occurs in ical I can even see the mail is in the sent folder in the mail application. But I don't receive any emails.
I have tried with two different mail addresses but with no luck. But if I right click the message in the sent folder, and click send again, and send it manually it works.
I am aware that this is a OSX issue but maybe someone know something?
As far as I could see, this is the most up to date method to handle ical alarms in Indigo?
