Liebe Gemeinde,
ich betreibe einen Postfix-Server mit Multi-Instanz-Setup. Die ersten drei Instanzen funktionieren gut. Die Instanz, die Submission auf Port 587 bedienen soll, hat kein DNS. Unter /var/spool/postfix-sub/ fehlen die Verzeichnisse etc/ und lib/, die bei den anderen Instanzen angelegt wurden. Wie bekomme ich diese Verzeichnisse?
Die Instanz wurde erzeugt mit
postmulti -I postfix-sub -G sub -e create postmulti -i postfix-sub -e enable
/etc/postfix-sub/master.cf:
tlsproxy unix - - y - 0 tlsproxy submission inet n - y - - smtpd pickup unix n - y 60 1 pickup cleanup unix n - y - 0 cleanup qmgr unix n - n 300 1 qmgr tlsmgr unix - - y 1000? 1 tlsmgr rewrite unix - - y - - trivial-rewrite bounce unix - - y - 0 bounce defer unix - - y - 0 bounce trace unix - - y - 0 bounce verify unix - - y - 1 verify flush unix n - y 1000? 0 flush proxymap unix - - n - - proxymap proxywrite unix - - n - 1 proxymap smtp unix - - y - - smtp relay unix - - y - - smtp -o syslog_name=postfix/$service_name showq unix n - y - - showq error unix - - y - - error retry unix - - y - - error discard unix - - y - - discard local unix - n n - - local virtual unix - n n - - virtual lmtp unix - - y - - lmtp anvil unix - - y - 1 anvil scache unix - - y - 1 scache postlog unix-dgram n - n - 1 postlogd
Die Instanz läuft also im chroot und braucht irgendwoher Namensauflösung.
