yahoo can find your mail server ip so it is not a MX record trouble.
it seems that u have a connection trouble or something wrong with your mail server configuration.


btw: if u want more help u must tell us about your distro, network structure, mail server software and other details which can help us to identify the source of your trouble. dont forget to check mail and system logs.

good luck.

oh yes I have found out the problem...But I am looking for the sloution from you

open the pop3 and smtp ports. the following will do that.
iptables -A INPUT -p tcp -m multiport --dport 25,110 -j ACCEPT
