inetd.sec restricts connections from certain ip addresses. It has nothing to do with binding. Binding to an address would restrict connections to a certain ip address. inetd seems to bind to only to the port by using a wildcard for ip address. I don't think HP's inetd can bind to a certain address. At least, looking at the man page, I don't see an obvious way to do it. It would be a nice feature, though.

qpsmtpd-forkserver
qpsmtpd-forkserver(8) System Manager's Manual qpsmtpd-forkserver(8)
NAME
qpsmtpd-forkserver - Fork-on-demand server for qpsmtpd
SYNOPSIS
qpsmtpd-forkserver [options]
DESCRIPTION
qpsmtpd-forkserver is the qpsmtpd frontend script which binds to the SMTP TCP socket and forks as clients connect.
OPTIONS
--port port, -p port
Binds to a specific port, instead of the default 2525.
--user user, -u user
On startup, switch to run as user instead of the starting user. Applies only when started as root (as is normal when listening on
port 25).
--limit-connections limit, -c limit
Accept at most limit simultaneous connections. Inbound connections beyondthis limit will be deferred or refused.
--max-from-ip limit, -m limit
Accept at most limit simultaneous connections from any given IP address; does not override --limit-connections, if set.
--listen-address addr, -l addr
Bind to the local address addr, instead of the default behavior of binding to all interfaces. Can be specified multiple times to
bind to more than one interface or local address.
--detach, -d
Detach from the controlling terminal at startup, to run as a standalone daemon. See also --pid-file.
--pid-file filename
Upon startup, and after daemonizing if applicable, write the process ID to filename, for use by sysvinit control scripts or similar
utilities.
