It's very simple to config  incoming connect rate  by
confCONNECTION_RATE_THROTTLE  and confMAX_DAEMON_CHILDREN .

But when sendmail delivery mails to the other mail host,
how to limit max connect num per host( or domain).

Is there a good and simple solution?

Could you describe "the real life problem" you face?

AFAIK what you want is not supported directly but sendmail is a flexible
program so most likely the problem may be fixed another way.

Maybe I can use a firewall rules to fix it.

I was under the impression he was asking about :

define(`confHOST_STATUS_DIRECTORY',`.hoststat')dnl
 define(`confSINGLE_THREAD_DELIVERY',`tru
e')dnl

But that's 1 outgoing connection per destination host and sometime I
would have liked if it was settable to 2 or 3.

Although when I use single thread delivery, I also reduce the queue
runner spawn time (-q3m) or even use "define(`confDELIVERY_MODE',`q')".

Have you tried to use separate queue group?
[ set number of queue runners per queue groups ]

The group may be associated with custom mailer so
* simple single mailertable entry will select it
* the mailer may be configured as "expensive"
(no "at once" delivery attempt)
* You may use persistent queue runner
