I manage 6 ISPC servers at this moment all with the add-ons: Postgrey Ryzor Pyzor Dcc FuzzyOCR RBL from 9 sources And have started to receive some very nice testimonials from customers and users praising our efforts to reduce that spam to zero. Except one elder dame allocated each morning to work thought her mail and she now complain about only receiving one legitimate mail instead of 50 spam’s and she does not know what to do with her mornings anymore! Beside the point, one of my OLD server that still run FC1 and OLD SpamAssassin and some funny software could not be converted yet, so I forwarded the mail to one of the new servers. On inspection of the Header records I detected that the mail that was scanned on the OLD box is NOT re-scanned on the new and therefore passes a high volume of spam onto the user. Can someone help me to configure the SpamAssassin to re-check for spam. It seems to look like once X-Spam headers are in mail the next server skip the tests! EDIT:I can not just switch off the SpamAssassin on the first box as only some mail are forwarded.
