How can I look up a DNS MX record for a given server in Java?

问题

Anybody knows how to get MX address (from for example gmail.com) in java using standard libraries? Or do I need to download external one?

I'm using netbeans if it can be helpful (if it provides something for this).

回答1:

I was also searching for standart lib for this in java. Unsuccessful.

Then I have used dnsjava.

private Record[] lookupMxRecords(final String domainPart) throw TextParseException
{
    final Lookup dnsLookup = new Lookup(domainPart, Type.MX);
    return dnsLookup.run();
}
