Possible in sendmail but if it takes rewrite rules, very demanding. You mean incoming mail will be relayed to one of several hosts by domain? Nothing delivered locally? Or are you talking about outgoing mail? ACL is a file permission thing, usually.
Postfix is pretty standard about this sort of thing:

SHOWQ(8) System Manager's Manual SHOWQ(8)
NAME
showq - list the Postfix mail queue
SYNOPSIS
showq [generic Postfix daemon options]
DESCRIPTION
The showq daemon reports the Postfix mail queue status. It is the program that emulates the sendmail `mailq' command.
The showq daemon can also be run in stand-alone mode by the super-user. This mode of operation is used to emulate the `mailq' command while
the Postfix mail system is down.
SECURITY
The showq daemon can run in a chroot jail at fixed low privilege, and takes no input from the client. Its service port is accessible to
local untrusted users, so the service can be susceptible to denial of service attacks.
STANDARDS
None. The showq daemon does not interact with the outside world.
DIAGNOSTICS
Problems and transactions are logged to syslogd(8).
BUGS
The showq daemon runs at a fixed low privilege; consequently, it cannot extract information from queue files in the maildrop directory.
SEE ALSO
cleanup(8) canonicalize and enqueue mail
pickup(8) local mail pickup service
qmgr(8) mail being delivered, delayed mail
syslogd(8) system logging
