slow down with Use SpamAssassin = yes

[Julian Field]

What version of MailScanner are you using? Do you have a setting
         Compile SpamAssassin Once = yes
in your mailscanner.conf file? If you are running an old version  that
doesn't have this setting, then I advise you upgrade.

Using either a spamc/spamd solution or a milter solution won't go any
faster than new versions of MailScanner (in the end of the day, the
underlying SpamAssassin engine is all perl).
