Kalo saya coba belajar menganalisis: [root@mailserver ~]# host ema.gov.sg ema.gov.sg mail is handled by 5 mailkdh2.email.gov.sg. ema.gov.sg mail is handled by 5 mailctp1.email.gov.sg. ema.gov.sg mail is handled by 5 mailctp2.email.gov.sg. ema.gov.sg mail is handled by 5 mailkdh1.email.gov.sg.Thank you. [root@mailserver ~]# host 160.96.208.33 33.208.96.160.in-addr.arpa domain name pointer mailkdh1.email.gov.sg. --> Bukan sgkdhmc321.resoe.gov.sg Problem DNS server pengirim karena recordnya tidak tepat?? Apakah solusinya? Mohon advisenya. Sincerely yours, Komar --[MDaemon-L]------------------------------------------------ Milis ini untuk Diskusi antar pengguna MDaemon Mail Server.
