Usually when I get new emails in my inbox (tiscali), they are highlighted as bold and the tally on the starter page says Inbox (5), say, if there are 5 new emails. However lately I've had emails coming straight into my inbox and they haven't been highlighted and they haven't been recorded in the tally. Consequently, I've missed them in my initial glance at my inbox in the mornings, which is quite annoying.
So why are these emails not being flagged up?
