Is anybody else seeing this? Instead of getting the [spam] tag added the mail comes through as a SpamAssasin report with the original message attached. Unfortunately the message still has the original title without the tag.
This is how the message starts:
Spam detection software, running on the system "ptb-mxcore20", has
identified this incoming email as possible spam. The original message
has been attached to this so you can view it (if it isn't spam) or label
similar future email. If you have any questions, see
the administrator of that system for details.
