Membuat mail server pada linux debian 12 berbasis cli dengan ketentuan sebagai berikut:
\n1. ip address server 192.168.10.10\/24
\n2. install apache2, postfix dan dovecot
\n3. konfigurasi apache, posfix dan dovecot agar bisa mengirim email dan terima email.
\n4. install bind9 dan konfigurasi domain sekolah.web.id dan belajar.web.id
\n5. kedua domain bisa saling berkirim email
\n6. buatkan sub domain untuk masing-masing dengan nama webmai.sekolah.web.id dan mail.belajar.web.id
\n7. install dan konfigurasi roundcube untuk kedua domain tersebut<\/p>\n

Penyelesaian<\/p>\n

\n
Konfigurasi Mail Server multi-domain pada Debian 12 membutuhkan pengaturan DNS lokal (BIND9), Mail Transfer Agent (Postfix), Mail Delivery Agent (Dovecot), database MariaDB, dan Webmail Client (Roundcube) dengan Apache2.<\/div>\n
