It fails in like 0.1% of the messages. ~5k Mails get moved to the
frozen directory aday and 3-5 of this fail.

exim is configured in a MailScanner setup. So mails go like this:

exim_in (smtp_listener) -> mailscanner -> exim_out (queue runner)

But this should not be the problem, because MailScanner uses the
correct locking mechanism and mails which are frozen had gone through
atleast one delivery attempt... or do i miss something?
