some spam mails stored in spam folder, some not

Hi,

For some reason in my account only some SPAM messages get stored in the spam folder and some are stored in my regular inbox. both of them look like this:

Spam detection software, running on the system "mybigassserver.sometld.cc", 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

Anyone got a clue?

Horde configured to route spam but not working

Hi, I have Horde configured to route spam to the spam mailbox, but it is not doing it. All mail marked spam is still going to inbox. Why would this be?

Have enabled SpamAssassin on your server?
