This dialog shows up whenever you have POP filtering switched on and messages were found on the server that exceed the threshold size you defined for the POP account. Now you have the chance to decide what you want to do with that message. The options are Download (green), Download later (yellow with egg watch) and Delete from server (red X). Be cautious with the delete option, since once you deleted a mail from the server, there is no way to undelete it again.
Este diálogo aparece sempre que o filtrado de POP estea activado e existan mensaxes no servidor que execedan o tamaño límite que definiu para a conta de POP. Entón ten a oportunidade de decidir o que quere facer con esa mensaxe. As opcións son Transferir (verde), Transferir Máis Tarde (amarelo cun reloxo) e Eliminar do servidor (X vermello). Tente ben coa opción de eliminación, dado que unha vez que elimine unha mensaxe do servidor non hai xeito de recuperala.
