So, now I sit here, waiting for a mail, and guess what? It won't come. Because none of my mail apps are able to connect to the mail servers! I tried on my iPhone (iOS 6.0.1), on my iPad (iOS 5.something), on my MacBook Pro and on my Mac Mini (OS X 10.8.2). And no single one of these machines is able to connect to mail servers that use POP, IMAP or SMTP (it shows it connected properly with SMTP servers, but it can't download mails). The only thing that still works is - who would have guessed it - Microsoft Exchange. :O Any ideas what goes wrong today? I didn't change a single setting and until today everything worked perfectly.
