Hi,

We're using qmail-scanner for a couple of years now, with no real problems.
But last night something strange happened. A user complains that he has
received some spam. The subject of these mails is tagged with what we have
configured in local.cf, in this case: "**** SPAM? (20.3) ****". We have
configured qmail-scanner with the --sa-quarantine option so that mails with
a score >= 7 will be quarantined. This is weird, the mail should have gone
to quarantine. I'm sure that this subject was added by our server, as the
qmail-queue.log file shows the original subject without that score. The rest
of the qmail-queue.log shows the following:

So it does not detect it as spam, but it does alter the subject with a score
of 20.3?  One reason I could imagine, is that the message is a bounce, and
that the bounce contains a copy of the original message, which in turn
contains a line: "X-Spam-Status: No, hits=0.6 required=5.0". Maybe somehow
qmail-scanner is confused and takes the 0.6 score instead of the 20.3 ?

Any help is appreciated!


Greetings,
Tom
