They are caused by spamd not returning correct content: Qmail-Scanner pipes the message to spamc, which pipes it into spamd. spamd is meant to return an altered version (including X-Spam-Status header), and if Qmail-Scanner doesn't see such a header, it treats that as a temporary failure (actually, it tries 3 times before giving up). Assuming it works most of the time, the likely issue is a busy spamd that is timing out once in a while before it can push the results back to spamc. As long as it doesn't happen too often, it's fine. If it happens nearly all the time, then you should look to what you can do to improve spamd: more children/bigger servers/etc -- Cheers Jason Haar Information Security Manager, Trimble Navigation Ltd.
