SpamAssassin has created a folder in your Web Mail and Pine folders.
SpamAssassin appends this heading to any message it flags as spam.
“Spam detection software, running on the system "sun3.oulu.fi", 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 block similar future email."Managing the spam_assassin folder in Web mail:
