Question Mark on Inbox view

Can someone tell me the meaning/reason for the little circle with a question mark that appears next to the senders name in R6 inbox? It just shows up next to some emails and not all.

Create a new memo, then open the “Delivery options” dialog. Look at the Moods – one of them is “Question”.

Perhaps your company has implemented a spam/virus/content-screening process which marks questionable emails this way – in which case, it’s not part of the functionality of the Lotus product.
