Ahsan,
just for didactical purposes, the following should (?) be the minimum
code needed for your matcher (you need jdk 1.5):
--------------
package serveravailability.matcher;
import java.io.IOException;
import org.apache.mailet.GenericRecipientMatcher;
import org.apache.mailet.MailAddress;
import java.net.InetAddress;
public class SAMatcher2 extends GenericRecipientMatcher {
public boolean matchRecipient(MailAddress recipient) {
try {
InetAddress address =
InetAddress.getByName(recipient.getHost());
if (address.isReachable(30000)) {
return false;
} else {
return true;
}
} catch (IOException ex) {
return true;
}
}
}
--------------------
As you see, it extends GenericRecipientMatcher, not GenericMatcher, so
it will work independently for multiple recipients.
I haven't tested it (and won't test it). Just compiled.
You don't need the mailet. use Bounce as I told you.
Anyway, it does not make sense to ping the domain name of a recipient's
address, as it would work only if it resolves to the ip of the mail
server specified in an MX record of the domain itself, and this
situation may be common only for small domains. Moreover, it is not sure
that an existing and running mail server does answer to a ping.
Read what Stefano wrote you some days ago.
Good luck with your assignment.
