Switching back to qmail from postfix in plesk 9

I prefer PostFix but over the years have become used to qmail on plesk and have spamdyke working for greylisting which is better than the plesk version of greylisting.  To switch back to qmail use this command.

[sourcecode]/usr/local/psa/admin/sbin/autoinstaller –select-release-current –install-component qmail[/sourcecode]
