There is a bug in handling that, but probably doesn't help with your actual problem: http://hg.dovecot.org/dovecot-1.0/rev/ba3c6dc3126c > sending this command to a cyrus imap server does not fail. With Cyrus 2.2.13 I see: 1 APPEND INBOX () "14-Mar-2007 14:20:45 +0100" {0+} 1 NO System I/O error You should anyway figure out why you're trying to save a zero byte mail.
