Right. Use ICS TDnsQuery component. It is good programming practice to split
into different component. SMTP component handle SMTP protocol, DNS component
handle DNS requests
such as MX record. You are free to combine both components in your own
component (or application) if
it happend that it is useful for you :-)

Look at the NsLookup demo included with ICS.
