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

  postmap hash:/etc/postfix/virtual_mailbox_domains.txt
-> erzeugt ''/etc/postfix/virtual_mailbox_domains.txt.db''
Domain nachschlagen testen:
  postmap -q example.com hash:/etc/postfix/virtual_mailbox_domains.txt
-> ''yes''
<file txt /etc/postfix/virtual_alias_maps.txt>
# 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
-> ''user1@example.com''
  postmap -q user1@example.com hash:/etc/postfix/virtual_alias_maps.txt
-> ''user1@example.com''

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

<file txt /etc/postfix/main.cf>
mydestination = localhost

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>
  postfix reload

===== testen =====
Client:
  swaks --from user1@example.com --to user2@example.com -s example.com -a -au user1@example.com -ap xxxxxx
-> ''Ok: queued as 46AE13EB41''

Server:
  journalctl -g 46AE13EB41
-> ''postfix/lmtp[…]: 46AE13EB41: to=<user2@example.com>, relay=example.com[private/dovecot-lmtp], …, status=sent''
