Zentrales Postfachverzeichis

Wenn man Postfachbenutzer hat, die keine Systemkontos haben, so bietet sich ein zentrales Verzeichnis für alle Postfächer an

# /etc/postfix/main.cf:
virtual_mailbox_domains = f-r-e-i.de
virtual_mailbox_base = /home/Mail/
virtual_mailbox_maps = hash:/etc/postfix/vmailbox
virtual_minimum_uid = 1030
virtual_uid_maps = static:1033
virtual_gid_maps = static:533

# /etc/postfix/vmailbox:
wk@f-r-e-i.de    f-r-e-i.de/wk
# Comment out the entry below to implement a catch-all.
# @ef-r-e-i.de     f-r-e-i.de/catchall

Aktivieren der Konfiguration:

postmap /etc/postfix/vmailbox
/etc/init.d/postfix restart
