Instalasi Squirrelmail

Siapkan POP3, IMAP & SMTP Server

apt-get install apache2 php5 php5-xmlrpc php5-mysql php5-gd php5-cli \
php5-curl mysql-client mysql-server dovecot-common dovecot-imapd \
dovecot-pop3d postfix squirrelmail squirrelmail-decode

Pastikan dovecot mendukung imap, biasanya default-nya sudah ok

vi /etc/dovecot/dovecot.conf

protocols = imap pop3

Beritahu Apache bahwa ada Squirrelmail dengan cara

cp /etc/squirrelmail/apache.conf /etc/apache2/conf.d/squirrelmail.conf

Konfigurasi Domain Squirrelmail

/usr/sbin/squirrelmail-configure

2 -> 1 -> domain.id -> S -> Q

Ubuntu versi 11.04, edit konfigurasi Dovecot

vi /etc/dovecot/dovecot.conf

mail_location = mbox:~/mail:INBOX=/var/mail/%u

Ubuntu versi 11.10 ke atas, edit konfigurasi Dovecot

vi /etc/dovecot/conf.d/10-mail.conf

mail_location = mbox:~/mail:INBOX=/var/mail/%u

Restart Server

/etc/init.d/dovecot restart
/etc/init.d/apache2 restart
/etc/init.d/postfix restart

Webmail dapat di akses melalui

http://ip-address-server/squirrelmail

Konfigurasi SMTP Postfix

Sebaiknya SMTP Server Postfix diberitahu domain, relayhost, IP lokal

vi /etc/postfix/main.cf

mydestination = sekolah, localhost.localdomain, localhost, sekolah.sch.id
relayhost = smtp.telkom.net
mynetworks = 127.0.0.0/8 [::ffff:127.0.0.0]/104 [::1]/128 192.168.0.0/16
