tutorial debian 6

Mail server adalah sistem yang memungkinkan pengguna (user) untuk dapat mengirim dan menerima surat elektronik (Email) satu sama lain dalam satu jaringan atau dengan internet.

Sedangkan webmail server yaitu sarana yang memungkinkan user dapat mengakses email melalui web. Jadi mail server adalah mesinnya dan webmail server adalah interfacenya. Mail server yang akan kita bahas disini adalah dengan menggunakan postfix dan dovecot. Sedangkan untuk webmailnya kita menggunakan squirrelmail. Untuk mempersingkat mari kita langsung ke cara

menginstallannya di linux debian :

Install Postfix

Postfix was not set up. Start with  cp /usr/share/postfix/main.cf.debian /etc/postfix/main.cf . If you need to make changes, edit /etc/postfix/main.cf (and others) as needed. To view Postfix configuration values, see postconf(1). After modifying main.cf, be sure to run '/etc/init.d/postfix reload'.

Pertama kita install postfix dengan perintah di atas, kemudian pilih No Configuration dulu karena kita akan mengkonfigurasinya lagi setelah tahap penginstallan postfix selesai.

1	naditkj:~# dpkg-reconfigure postfix

Kemudian isi system mail name misalnya nady.net nama tersebut digunakan untuk domain alamat email user anda misalnya nama@nady.net (Saya sarankan samakan dengan nama domain anda di DNS) agar lebih mudah mengkonfigurasinya.

Ubah hingga menjadi ip localhost, ip network anda seperti contoh di atas. 127.0.0.0/8 itu adalah ip localhost sedangkan 192.168.0.0/24 itu adalah network pada jaringan kita. (Bisa di ubah sesuai dengan IP anda). Selanjutnya pada pilihan use mail delivery pilih No. Dan berikutnya enter saja hingga tampilan pemilihan IPv4 dan IPv6 pilih All saja.

Install Dovecot (IMAP & POP3)

Penginstallan postfix telah selesai, selanjutnya kita install dovecot untuk mengaktifkan POP3 dan IMAP.

Setelah penginstallan dovecot POP3 dan IMAP mari kita konfigurasi.

1	naditkj:~# nano /etc/dovecot/dovecot.conf

Selanjutnya tekan CTRL+W lalu cari keyword disable_plaintext_auth edit hilangkan tanda pagarnya kemudian ganti yes menjadi no.

Kemudian cari mail_location dan ganti menjadi seperti ini:

Tahap dovecot sudah selesai selanjutnya kita install squirrelmail untuk interfacenya.

Install Squirrelmail (Webmail)

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25

Setelah install squirrelmail selesai maka kita konfigurasi apache untuk menginclude data squirrelmail tersebut dengan cara

1	naditkj:~# nano /etc/apache2/apache2.conf

kemudian pada baris paling bawah tambahkan

1	Include /etc/squirrelmail/apache.conf

Membuat User Email

Setelah selesai semuanya mari kita membuat misalnya 2 user email untuk percobaan

1 2 3 4 5 6 7 8 9 10

naditkj:~# useradd admin -s /bin/false -m naditkj:~# passwd admin Enter new UNIX password: Retype new UNIX password: passwd: password updated successfully naditkj:~# useradd umi -s /bin/false -m naditkj:~# passwd umi Enter new UNIX password: Retype new UNIX password: passwd: password updated successfully

Di atas kita membuat 2 user yaitu admin dan umi.

Restart Semua Servis yang bersangkutan

1 2 3 4

naditkj:~# /etc/init.d/apache2 restart Restarting web server: apache2. naditkj:~# /etc/init.d/dovecot restart Restarting IMAP/POP3 mail server: dovecot.

Pada Gambar tersebut mengirim dari admin@nady.net ke umi@nady.net dan silakan logout dan coba login ke umi@nady.net maka jika berhasil yaitu seperti berikut:
