Server kami memang tidak mau berhubungan dengan server-2x yang tidak punya legitimasi untuk sending mail. Sejak tahun 2009 kami mengaktifkan sender host checker seperti juga yang digunakan banyak member milis ini. Server yang punya legitimasi (authorized) for sending mail 1. Identitasnya harus terdaftar di internet. $ host postman.localdomain Host postman.localdomain not found: 3(NXDOMAIN) 2. punya valid pointer record (PTR) record yang sesuai dengan identitas server. $ host 202.57.2.118 Host 118.2.57.202.in-addr.arpa. not found: 3(NXDOMAIN) semua kriteria itu tidak dipenuhi oleh relayhost Anda. Info lebih lengkap bisa dibaca disini http://www.mail-archive.com/[email protected]/msg20502.html Saya sudah buatkan pengecualian dengan mendaftarkan kedalam tabel/daftar server yang malu-2x in <G> agar diperbolehkan connect untuk mail yang masuk berikutnya.
