Oh, yeah the count doesn't go over 99+, but the message keep coming in and are kept. It's not like a
full box you can't put any more into. Private or public. It doesn't say, sorry too full can't take your mail.
Don't worry i've been giving it a shot for years, and can only get rid of newer ones first. Can't as far as i know
go back to the beginning to delete years old ones first. Maybe there is a way to do that. Not that i know of yet.
"The little red number denotes 'Unread messages' for 24 hours."
Can't be right as i read all the messages as they come in. The "unread" appears to be superfluous unless you mean
it means 99+ messages that have not been read for 24 hours. Like mail at home that gets put aside and forgotten.
