WARNING: starting to adjust these can potentially produce interesting
changes (some good, some bad). I would recommend you test this on a
testbed before implementing it in a production system.
These 3 changes in sendmail.mc (and then a m4 compile of sendmail.mc)
define(`confMAX_DAEMON_CHILDREN', 10)dnl
define(`confCONNECTION_RATE_THROTTLE', 10)
define(`confSINGLE_THREAD_DELIVERY',false)
will add these 3 lines to sendmail.cf
O MaxDaemonChildren=10
O ConnectionRateThrottle=10
O SingleThreadDelivery=false
I'm not sure of what Sendmail defaults for those values, but basically
those statements allow up to 10 simultaneous child processes (inbound
and outbound).
