Hi there is a BIG problem when you add a new event on the calendar, if 
you set the option ?Email? of the Alarm Notification,  i.e. the mail 
?that is a BAD MAIL? (yea clearly is not an email format and that's 
the point), when the alarm come on, the interface will fail (a BIG 
one), and will get:

And the user won be able to use any interface option (IMP, Calendar, 
Address Book, anything) until alarms event has gone.  In fact the 
script ?horde-alarms? won work either (so nobody won be able on 
receive a mail notification) and the error will be:
