We switched to a new server. And imported all mails form the old account. Now in Mail all the attachments are shown. But on the iPad, the icon is shown that there is a attachment, but no attachemt is in the mail. This is only with the imported mails, all new mails are working correctly with the attachments. How to solve this ?
Mac mini, OS X Mavericks (10.9.2), OS X Server 3.1.1
