Have you tried setting Active after you have the other
properties set?
| Quote: | IdDNSResolver1->Host = myIspDnsServerIP;
IdDNSResolver1->QueryRecords = TQueryType() << qtMX;
IdDNSResolver1->Resolve("diskwave.com");

I don't see Resolve as a method. There is ResolveDNS and
ResolveDomain.

I'm not sure what you're doing here ... :-p

If IPList is blank, then you're not entering the loop or your
dynamic cast never resolves to a TARecord. Do you know which
is the case? Try this (guessing at what you wanted to do with
IPList):
ShowMessage( IntToStr( IdDNSResolver1->QueryResult->Count ) );
for(int i=0; i < IdDNSResolver1->QueryResult->Count; ++i)
{
static bool TARecordNotFound = true;
TARecord* ARecord = dynamic_cast<TARecord*>( IdDNSResolver1->QueryResult->Items[i] );
if( ARecord )
{
if( TARecordNotFound )
{
ShowMessage( "Found a TARecord" );
TARecordNotFound = false;
}
String s;
s.sprintf( "%d ; %s", i, ARecord->IPAddress );
IPList += s;
}
}
ShowMessage( IPList );

Above is the code I am using to resolve the mx record of a domain.
When I try diskwave.com as the address to be resolved it shows a blank
message.
Should it not show the mx record?

Presumably, but it's doubtful one was found. Try using nslookup, dig, or
host to query the MX record for diskwave.com - there is none. The record is
supposed to be provided by diskwave.com itself, but there's no DNS server
running at that address.

Or someone forgot to update the mx record.
Someone like me.
