Mike keeps getting a notification of a new email even though he's already read it. Leo says that there's a setting in his mail that will delete email after he downloads it to his phone. That's a POP feature. IMAP should be able to keep the mail on the server and register it as having been read. If it's not doing that, Mike should check his settings. He could also talk to his IMAP provider. They may have an issue. It could be an indexing problem. He should consult this page at godaddy.com for more.
