First, which address is which. Using the FQDNs you mention below, I find
they both resolve, as follows:
inf.uajy.ac.id = 202.149.81.61
mail.uajy.ac.id = 202.149.81.55
Replies to your specific questions assume these are the right FQDNs and I am
resolving them to the right addresses. If I am not ... then that is where
you need to look for the problem.
So, the first thing is to confirm that the two addresses are resolving
correctly, externally.
Second, I cannot do a reverse lookup on either of these addresses. The results:
collier:/usr/src/linux# host 202.149.81.61
202.149.81.61 does not exist, try again
collier:/usr/src/linux# host 202.149.81.55
202.149.81.55 does not exist, try again
This is a DNS problem that should be fixed. It might be causing some of your
failures (see below).

inf=61 *is* ping'able from here, but mail=55 is *not (times out)

My browser returns home pages of both addresses:
http://202.149.81.61/ = "Teknik Informatika"
http://202.149.81.55/ = "UAJYWebmail"
The text of neither home page is in English, so I can't really tell you more
than that about them. The second one at least seems right, given the match
to the "uajy" in the FQDNs. And the first says it is the Website of
"www.inf.uajy.ac.id", so it too is probably right (your domain, if not your
actual host).

The DNS problem (no reverse lookups) could be the cause of your mail failures.

How do these local mail sends fail? Can you telnet to port 25 on both
addresses? If I try, I get different results:
collier:/usr/src/linux# telnet 202.149.81.61 25
Trying 202.149.81.61...
Connected to 202.149.81.61.
Escape character is '^]'.

This says to me that (again, assuming I have the addresses right) there is
something wrong with your MTA, since it (or something) is *listening* on
202.149.81.55:25 but not responding properly.

Given the differences between my results and yours, I can only suggest that
you report the conditions of your tests more completely.
