Hi everybody,

a friend of mine asked me to look at his mail server as he is on
holiday at the moment. The users don't receive emails at the moment,
postfix returns temporary failure when trying to deliver. He told me
everything worked correctly until cyrus went out of disk space. This
seems to happen frequently on this server, a new server is already
ordered. He cleaned up the disk and restarted postfix and cyrus but
this time the mails are not delievered any more. Postfix says "mail
deferred" and "temporary failure". I searched the last few days but
couln't find anything that helped.

Below are the log messages and configuration. Hope I didn't forget
anything. Any ideas?

Thanks for your help,

Joerg

The log messages:
