iCal doesn't send invitations
I'm using iCal and Mail. For any event I set in iCal the invitees doesn't get any invitation. The same happens when I receive and invitation for an event. If I accept the invitation, that who is inviting me, never receives the acceptance for that invitation. For any modification of the event, the application does the updating process but apparently it doesn't generate the corresponding e-mails. (My e-mail address is a gmail address). This problem started just after I upgrade to Lion. Any sugestions!!!
