iPhone Mail icon does not show number of messages
iphone mail icon does not show number of messages. Notifications and badge are turned on

That is strange as you have already turned on notifications and badges for mail. Keep in mind that mail will only show the number of unread emails, not the total number of emails in your in-box or anything like that. That is perplexing. Try the obvious and restart your iPhone if you haven't already.
Just in case it helps someone else with the same issue, I'm going to post these screen-shots which show how to turn on Notifications and badges for mail, which you have already done.
From the home screen: Settings->Notifications->Mail : Turn on notifications. Turn on badges. Sorry I don't have a better answer than that.
