do you feel that system goes slower?
i think it's just the matter of calculation method - 6.* may calculate it 
different way.

just change in your sendmail config the values in place of xx

define(`confQUEUE_LA', `xx')
define(`confREFUSE_LA', `xx')


as just accepting mail isn't a problem i set confREFUSE_LA very high
