New MailScanner Script v2.59

Changes:

• Fixed a problem where DCC was not working with SpamAssassin when running through MailScanner (worked fine through SA directly) caused by undocumented changes in the spam.assassin.prefs.conf MailScanner configuration file and obvious bug in the way MailScanner is calling SA, as SA is behaving differently when called indirectly through MS than if run directly.
