SOGo, GOSa, Postfix, Amavis, Dovecot auf Ubuntu Server 12.04

Ich habe kürzlich mein Mailsystem auf LDAP umgestellt und dann auch gleich noch SOGo installiert um CalDAV und CardDAV zu haben. Hauptsächlich zur Nachvollziehbarkeit für mich selbst sind hier die Schritte, die ich auf einem frisch installierten Ubuntu 12.04 durchgeführt habe. Vielleicht hilft es ja auch jemand anderem. Ich hoffe es ist alles komplett. Wenn das mal jemand nachgemacht hat, würde ich mich über einen Kommentar freuen. Auch für Verbesserungsvorschläge der Konfiguration wäre ich dankbar.

Alle Shell eingaben sind als root durchzuführen, wenn nicht anders angegeben. Als hostname verwende ich hier mail.example.com. Die LDAP Base ist dc=example,dc=com.

Zunächst habe ich erstmal etckeeper installiert, da ich meine Konfiguratinsdateien gerne unter Versionsverwaltung habe:

apt-get install etckeeper git

etckeeper init
etckeeper commit

GOsa wird zur Verwaltung des LDAP Systems genutzt.

apt-get install slapd gosa-schema gosa gosa-plugin-systems gosa-plugin-mail ldap-utils

Ich bevorzuge das rfc2307bis Schema für LDAP-Gruppen. Wer das nis Schema benutzen möchte, kann den nächsten Schritt weglassen.

service slapd stop
rm /etc/ldap/slapd.d/cn=config/cn=schema/cn={2}nis.ldif

Hier geht es für alle weiter. Es werden die von GOsa benötigten Schemata zum LDAP hinzugefügt:

add: olcDbIndex
olcDbIndex: uid eq
olcDbIndex: mail eq
olcDbIndex: cn eq
olcDbIndex: gosaMailAlternateAddress eq
olcDbIndex: postfixMyDestinations eq

Auf http://mail.example.com/gosa den Anweisungen folgen. Je nachdem ob man die rfc2307bis Gruppen im LDAP aktiviert hat, oder nicht muss die entsprechende Einstellung im GOsa Setup gewählt werden.

Nachdem man die generierte GOsa Konfiguration gespeichert hat, muss zunächst ein neues System in GOsa angelegt werden:

In diesem System kann nun ein neuer Mailserver angelegt werden:

Hierbei ist es wichtig, dass unter dem Punkt “Domänen, für die Mail angenommen wird” der Hostname des Servers eingetragen wird. In diesem Fall also mail.example.com.

Als nächstes werden postfix, dovecot und amavisd-new installiert. pyzor und razor verbessern die SPAM-Erkennungsrate, können aber weggelassen werden, wenn man das möchte. clamav-unofficial-sigs sind SPAM-Signaturen für clamav. mutt ist optional, aber hilfreich beim testen. phpldapadmin ist auch optimal, aber wenn man mal schnell in der LDAP-Datenbank rumeditieren will, ist es ganz hilfreich.

Das auth_username_format wird geändert, damit man sich mit der uid anmelden kann. Ausserdem muss die system Konfiguartion durch die ldap Konfiguration ersetzt werden.

An dieser stelle sollte das Mail-System funktionieren.

Zunächst muss das SOGo repository in apt eingebunden werden. Ich habe den nightly build von SOGo 2.0 genommen, die Konfiguration sollte aber auch für SOGo 1.x passen.

/etc/apt/sources.list.d/sogo.list:

deb http://inverse.ca/ubuntu-nightly precise precise
#deb http://inverse.ca/ubuntu precise precise

Apache kann automatisch konfiguriert werden. Für mysql sollte ein Passwort gesetzt werden. phpmyadmin ist optional, aber hilfreich wenn man mal in der Datenbank rumfuhrwerken will. Ich werde spöter phpmyadmin dazu benutzen die SOGo Datenbank anzulegen, aber das kann man natürich auch über die shell machen.

apt-key adv --keyserver keys.gnupg.net --recv-key 0x810273C4
apt-get update
apt-get install sogo mysql-server phpmyadmin memcached

Es müssen noch ein paar module für den apache aktiviert werden:

a2enmod proxy
a2enmod proxy_http
a2enmod rewrite
a2enmod substitute

SOGo legt seine config im home directory des sogo Benutzers an. Das liegt allerdings nicht unter /etc und wird daher nicht vom etckeeper verwaltet. Das ist doof. Deshalb verschiebe ich das home directory nach /etc/sogo:

/etc/init.d/sogo stop
usermod -m -d /etc/sogo sogo

Jetzt wird auch die SOGo Datenbank angelegt. Ich habe phpmyadmin dazu benutzt:
