Mail shows downloading activity but no mails show up?
Since a few days, whenever i download mails the activity window shows incoming mails but it oftenly shows 3 or 10 incoming messages and afterwards i only see 1 in my inbox. There is also no mails in any of the other folders... Does anyone know what this is about?/Have a solution?
Is this a sign that i've been hacked?
Thanks for any advise!
