you should create sepparate tcpserver instances by "cloning" the run
scripts ( /services/qmail-smtp/run ) and changing the listening port
within these scripts.

I agree.

I suggest you create /service/qmail-smtpd{1,2,3} and in the run
scripts set tcpserver to listen on a different IP in the pool and
perform their different functions (IP{1,2} v IP{3})

If you want to have a single point of maintenance, you can use a UNIX
shell scripting trick.

Use ln to link the two other run scripts to the original.

# cd /service
# mv qmail-smptd qmail-smptd1
# mkdir qmail-smptd2 qmail-smptd3
# ln qmail-smptd1/run qmail-smptd2/run
# ln qmail-smptd1/run qmail-smptd3/run

The run file names are now aliases for the same underlying file.  Edit
the run file and add

dirName="$(dirname $0)"  # - OR  dirName=`dirname $0`

if [ "${dirName}" = "." ]
then
  dirName="$(basename $PWD)"
else
  dirName="$(basename ${dirName})"
fi

case "${dirName}" in
qmail-smtpd1)
TCP_HOST=192.168.1.30 # substitute your first actual IP addr here
;;
qmail-smtpd2)
TCP_HOST=192.168.1.31 # substitute your second actual IP addr here
;;
qmail-smtpd3)
TCP_HOST=192.168.1.32 # substitute your third actual IP addr here
;;
*)_echo "Unable choose a TCP_HOST"
exit 1
;;
esac

## Now later on in the run script use $TCP_HOST for the in the
tcpserver startup line
