The MX must be a name, not an IP. then add an A record for the name to
point to the IP.
... MX foo.example.com
foo.example.com A 172.16.0.4
but there is no need for an MX here. just use transport_maps:

The remote host does not handle mail for docu1.... .edu.my, so it
rejects it. If that host should handle such mail, you need to configure
it to do so (in postfix, add the domain to mydestination or other domain
classes). if the host does not handle such mail, then you should not
send this mail to that host.
PS. do you know what "coit" means in french?
