Disk full?
# du /var/qmail/queue
check /var/log/maillog or /var/log/messages for other reasons.

What distro are you running qmail on?

Do you have the packate SUIDPERL installed?

Also if you are running qmail-scanner try stopping it and then restart qmail.  If you are on a Redhat/Fedora solution make sure the server exim is not running.

My first answer will be, that I hav`nt tried it myself, yet a bit of web search has come up with this:

This message claims that the mail server has a problem with his work. That mean that you should open the log file, and probably learn for yourself what went wrong. The usual stuff is premissions: The qmail user is not allowed writing in the mail folder, qscand has no reading premission on the file, and can`t scan it for viruses, and all that stuff. Just make sure thease are ok.
