Java ip dns email host

I am trying to setup an smtp server.  I need a way to associate
bob@yahoo.com with yahoo's smtp server smtp.a2.yahoo.net or something.
I know that a dns server keeps an MX record to record a server for
email. I just need a way to translate @yahoo too smtp.a2.yahoo.net.

I tried using java.net.InetAddress.getByName("bob@yahoo.com")
Any other suggestions?

I don't know why it shows bxb@yxahxxo.xom it should be "bob@yahoo.com"

NOT bob@yahoo.com bob @ yahoo . com

As you said, you need to connect to a DNS server to get the MX record.
I found it was easier to do this by using C/C++.

/* E-mail.c */
#define User            "Yu.Song"
#define At              '@'
#define Warwick         "warwick.ac.uk"
int main() {
printf("Yu Song's E-mail: %s%c%s", User, At, Warwick);
return 0;}

I found out how!!! JNDI!!!

DirContext ictx = new InitialDirContext(env);
Attributes attrs1 = ictx.getAttributes("host1", new String[] {"MX"});
