Thank you Radoulov

Kdialog seems to be able to handle the output when given all the specific array elements:

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 ) );   
kdialog --title "KMX" --msgbox "# host -t MX $1 
${mxs[0]} ${ips[0]}
${mxs[1]} ${ips[1]}
${mxs[2]} ${ips[2]}
${mxs[3]} ${ips[3]}
${mxs[4]} ${ips[4]}
"  ; }; kmx google.com

Not sure, but I've found that kdialog is white-space specific. Perhaps it broke the output before because it was trying to write a whole array to one line. However, if that was the case it seems it would have not printed all the MX Records with this:

Code:

$ function kmx { mx=`host -t MX $1 | awk '{ print $7 }'`; 
ip=`host $mx | sed '/IPv6/d;/handled/d' | awk '{ print $4 }'`; 
kdialog --title "KMX" --msgbox "# host -t MX $1
$mx $ip";}; kmx google.com

Grant you that breaks the ips, but the $mx should have broken too if that was the case.

I know I could check the length of the array in this function, but I don't know if writing a loop to call each of these elements with kdialog would be possible or not. However, without the code being able to determine the number of MX Records and ip addresses itself would kind of defeat the purpose.

Any further suggestions appreciated.
