This should work with bash, zsh and ksh93:

Code:
kmx() {
  mxs=( $( host -t MX "$1" | awk '{ sub(/\.$/, x, $NF); print $NF }' ) )
  ips=( $( for _mx in "${mxs[@]}"; do host "$_mx" | awk '/has address/ { print $NF }'; done ) )
  msg=$(
    for ((i = -1; i++ < ${#mxs[@]} - 1;)); do
      printf '%s\t%s\n' "${mxs[i]}" "${ips[i]}"
    done  
    )
  kdialog --title "KMX" --msgbox "# host -t MX $1:
$msg"  
}

rwall(3RPC)						       RPC Library Functions						       rwall(3RPC)

NAME

       rwall - write to specified remote machines

SYNOPSIS

       cc [ flag ... ] file ... -lrpcsvc [ library ... ]
       #include <rpc/rpc.h>
       #include <rpcsvc/rwall.h>

       enum clnt_stat rwall(char *host, char *msg);

PROTOCOL

       /usr/include/rpcsvc/rwall.x

DESCRIPTION

       These routines require that the rpc.rwalld(1M) daemon be configured and available on the remote system indicated by host.

       rwall()	executes  wall(1M)  on	host.  The   rpc.rwalld process on  host prints msg to all users logged on to that system. rwall() returns
       RPC_SUCCESS if it was successful; otherwise a enum clnt_stat is returned which can be displayed using clnt_perrno(3NSL).
