I've noticed that some of the spam that gets through to my mailbox does not have the spamassasin headers necessary for the filtering system to place it in quarantine. Is there a reason why spamassasin would not add its headers(x-spam-score specifically) on some of the emails but would on others?
I would say that approx. 15-20% of all spam that I have received so far did not contain the x-spam-score header.
I've a stock configuration of the junk mail filter provided by DH.
Any ideas in this matter would be appreciated.
