debian | Mail-/Webserver installieren und konfigurieren

Hauptsächlich verwende ich meinen vServer als EMail-Server, da ich gerne selber meine EMails verwalte als einem Anderen zu vertrauen. Außerdem kann ich meinen Spam so filtern wie ich es will. Nebenbei stellt der vServer nur das Mail-Relay und leitet alle EMails an meinen privaten Exchange-Server weiter.

Aus Dokumentationszwecken hier die Installationsabfolge.

apt-get install –t etch-backports postfix mysql-server apache2 php5 php5-imap php5-mysql postfix-mysql dovecot-imapd phpmyadmin php-pear
apt-get install subversion
svn co https://postfixadmin.svn.sourceforge.net/svnroot/postfixadmin postfixadmin
mysql-Passwort setzen: mysqladmin –u root password ›NEUESPASSWORT‹

Postfixadmin

wget http://dfn.dl.sourceforge.net/sourceforge/postfixadmin/postfixadmin_2.2.1.1_all.deb
dpkg –i postfixadmin_2.2.1.1_all.deb
http://SERVER/phpmyadmin und einen User mit gleichlautender DB anlegen
/etc/postfixadmin/config.inc.php editieren und Datenbank-Einträge setzen
http://SERVER/postfixadmin/setup.php und Superuser anlegen
rm /usr/share/postfixadmin/setup.php
http://SERVER/postfixadmin aufrufen — sollte alles gehen
