You'll just have to double check the alerts settings and make sure that each Department is not disabling alerts. Otherwise you can check your templates to ensure nothing is wrong with the particular alert template.
As for the client portal tickets not showing up I'll quote my previous reply:
The only way it wouldn't show tickets is if there are no tickets with that user's user_id or if they are a collaborator on the tickets but you have the helpdesk configured to not show collab tickets.
So you will need to check to see if they are collaborator on those tickets and if so you'll need to enable the setting called Collaborator Tickets Visibility under Admin Panel > Settings > Tickets.
Cheers.
