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. 132.84.81.124.in-addr.arpa. domain name pointer personelalihdaya.com lihat informasi lebih rinci disini http://www.mail-archive.com/[email protected]/msg20502.html 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! --- -- syafril ------- Syafril Hermansyah MDaemon-L Moderators, running MDaemon 13.6.2 Beta B SecurityPlus 4.1.5 Harap tidak cc: atau kirim ke private mail untuk masalah MDaemon. -- --[MDaemon-L]------------------------------------------------ Milis ini untuk Diskusi antar pengguna MDaemon Mail Server.
