Here is somethings that I find useful on a busy mail host

define(`confMAX_DAEMON_CHILDREN',128)dnl
define(`confQUEUE_LA',8)dnl
define(`confREFUSE_LA',12)dnl
define(`confCONNECTION_RATE_THROTTLE',10)dnl

which becomes:

O MaxDaemonChildren=128

You might want to make this value a _lot_ lower ;-).

Kevin
