very well. the system load usually varies between 2 and 6, depending on
the number of ldap requests done by the mtas for mail routing. we expect
the load to reduce to 1-2, when we equip each mta with a local ldap
slave.
we will activate the new setup this week, maybe today ( can't tell now
coz i'm still enjoying my breakfast ;-) )
i'll monitor the modified setup and give you feedback on its
performance.
