It's not a bug, it's a feature :-)
The error message is exactly right...
$ $ nslookup tribun-putra.upm.edu.my
Server: localhost
Address: 127.0.0.1
Name: tribun-putra.upm.edu.my
Address: 202.184.36.9
$ nslookup 202.184.36.9
Server: localhost
Address: 127.0.0.1
*** localhost can't find 202.184.36.9: Non-existent host/domain
$
(I have a local cache nameserver running).
You don't have reverse DNS lookup working for that host, so sendmail
is (rightfully) complaining.
See your sysadmin people to fix it. And also add an MX entry (which
is also missing in the DNS records).
Cheers
