====== Postfix: virtuelle Domains und Benutzer in Textdateien ======
//in der Praxis würde ich LDAP oder eine Datenbank bevorzugen//

Voraussetzung: [[postfix-dovecot-imapd]] mit [[wpde>LMTP]] und [[dovecot-virtual-domains]]

===== Maps erstellen =====

''/etc/postfix/virtual_mailbox_domains.txt'' :
<file>
# postmap hash:/etc/postfix/virtual_mailbox_domains.txt
example.com yes
</file>

  postmap hash:/etc/postfix/virtual_mailbox_domains.txt
Domain nachschlagen testen:
  postmap -q example.com hash:/etc/postfix/virtual_mailbox_domains.txt

''/etc/postfix/virtual_alias_maps.txt'' :
<file>
# postmap hash:/etc/postfix/virtual_alias_maps.txt
postmaster@example.com  user1@example.com
abuse@example.com       user1@example.com
user1@example.com       user1@example.com
user2@example.com       user2@example.com
admin@example.com       user1@example.com,user2@example.com
</file>

  postmap hash:/etc/postfix/virtual_alias_maps.txt
Empfänger nachschlagen testen:
  postmap -q postmaster@example.com hash:/etc/postfix/virtual_alias_maps.txt
  postmap -q user2@example.com hash:/etc/postfix/virtual_alias_maps.txt

===== Postfix konfigurieren =====

''/etc/postfix/main.cf'' :
<file>
virtual_mailbox_domains = hash:/etc/postfix/virtual_mailbox_domains.txt
virtual_mailbox_maps    = hash:/etc/postfix/virtual_alias_maps.txt
virtual_alias_maps      = hash:/etc/postfix/virtual_alias_maps.txt

virtual_transport = lmtp:unix:private/dovecot-lmtp
</file>
