Public IP yang Anda gunakan tidak punya valid PTR record sehingga
dianggap tidak berhak kirim mail ke internet.
$ host 124.81.84.132
Host 132.84.81.124.in-addr.arpa. not found: 3(NXDOMAIN)
Minta ke ISP Anda (IndosatNet) untuk membuatkan PTR record pointing (map
to) ke FQDN host yang digunakan.

ini kutipan mengenai perlunya PTR record
http://ask.slashdot.org/story/03/05/07/1625211/are-ptr-records-important
---
PTR records are not necessary. They are not required for the internet to
work acceptably. But, PTR records do add considerable convenience to
network operation and they are a part of the DNS standard specification
so, they should be used.
The fact that mail systems that require PTR records before accepting
mail significantly reduces spam is reason enough that PTR records should
be required. I too experience a great deal of mail problems due to a
lack of PTR records but, it is worth the effort to stick to this policy.
If you don't have a PTR record, you can't send me mail!
