Postfix Installation (Debian Etch)

Only relayhost, accept only local mail.

apt-get install postfix

/etc/aliases - aliases für local accounts einrichten und umleiten auf externen user.

newaliases um hashmap zu erstellen

/etc/postfix/main.cf

relayhost parameter auf smtp-mailserver setzen.

/etc/postfix/sasl_passwd enthält mail-server user:password

relayhost = mail.math.fu-berlin.de

smtp_sasl_password_maps = hash:/etc/postfix/sasl_passwd

smtp_always_send_ehlo = yes

Dann postmap /etc/postfix/sasl_passwd

Für jeden user ein file (touch) in /var/mail erstellen. Für root sollte reichen, wenn alles nach root umgeleiten wird.
