EMail: Mempersiapkan Server eMail IPv6

Topology Jaringan

Client A --- Server A ------- Server B ---- Client B
2345::1000   2345::1          2345::2       2345::2000

Server A dan B

Siapkan SMTP, POP3 dan IMAP server.

sudo su
apt update
apt -y install postfix dovecot-core dovecot-imapd dovecot-pop3d

Pilih

• Internet Site
• Hostname - coba1.id - [Server A]
• Hostname - coba2.id - [Server B]

Edit (supaya tidak rewel, agak di longarkan security)

vi /etc/postfix/main.cf

my_hostname = coba*.id
my_destination = coba*.id
my_networks = [::]/0
smtp_bind_address6 = 2345::*
inet_protocols = all  (atau ipv6)

Dimana *=1 (server A), *=2 (server B)

Edit

vi /etc/resolv.conf
vi /var/spool/postfix/etc/resolv.conf

nameserver 2345::1

Restart

/etc/init.d/postfix restart
/etc/init.d/dovecot restart

Server A

sudo su
ip addr add 2345::1/64 dev enp0s3

Server B

Pada dasarnya tidak berbeda jauh dengan Server A, kecuali tidak ada DNS Server.

sudo su
ip addr add 2345::2/64 dev enp0s3

Client A dan B

Pada Client A dan B, instalasi

sudo su
apt -y install fetchmail postfix alpine thunderbird

Edit /etc/resolv.conf

vi /etc/resolv.conf

nameserver 2345::1

Setup alpine

alpine
S > C > 
    User Domain = coba1.id (untuk Client B coba2.id)
    SMTP Server = coba1.id/novalidate-cert (untuk Client B coba2.id)

Setup fetchmail (untuk Client B coba2.id)

cd ~
vi .fetchmailrc 
poll coba1.id protocol pop3 username "onno" password "123456"

Client A

sudo su
ip addr add 2345::1000/64 dev enp0s3

Client B

sudo su
ip addr add 2345::2000/64 dev enp0s3
