[X4U] iCal

[verduron]

I am finally using iCal [I forgot to pay my quarterly income tax!]
One thing which does not seem to work for me is the alarm system. I am 
setting the function " send an e-mail message", let's say, 5 days 
before the event to remind myself of the big day. So far all my tests 
have failed. NO e-mail message in my box. I have changed the parameters 
from 24 hours to several days but still NO message. What am I not 
understanding? TIA
