I dont have any smtp mailer!(clearly what do u mean by smtp mailer), coz am using sendmail. Is it different from that?
Second in the /etc/resolv.conf guess it's not misconfigured? coz when i issue the command i get:
nameserver "ip addresss of the mail server"
Third when i do nslookup yahoo i get:
server: "ipaddress of the mail server"
Address: "ipaddress of the mail server"#53
