Prosedur Membuat Auto Forward di Postfix
Auto forward akan membuat sebuah email yang masuk ke sebuah alamat email, juga akan masuk ke alamat email yang lain. Misal, setiap email yang masuk ke badu@risxxx.go.id juga masuk ke badu@itb.ac.id. Untuk melakukan hal ini, caranya seperti membuat mail alias.
1. Masuk ke sistem melalui SSH sebagai root tentunya.
2. Masuk ke folder user dimana akan kita buatkan auto forward-nya
[root@mail ~]# cd /home/risxxx/badu/
3. Buat lah file .forward atau cukup edit file .forward
[root@mail badu]#vi .forward
4. Setelah masuk ke vi editor, tambahkan 2 baris berikut ini ke dalam file .forward
badu@risxxx.go.id
badu@itb.ac.id
5. Lalu simpan dan selesai
6. Jangan lupa tes fungsinya
