Vielen Dank für Deine Unterstützung!
Bei mir kommt eine völlig andere Ausgabe:
root@kn-mc01:/opt/mailcow-dockerized# docker exec $(docker ps -qf name=postfix-mailcow) postconf -h tls_high_cipherlist
/usr/sbin/postconf: warning: /opt/postfix/conf/main.cf, line 203: overriding earlier entry: message_size_limit=104857600
aNULL:-aNULL:HIGH:@STRENGTH
Dovecot scheint zu passen:
root@kn-mc01:/opt/mailcow-dockerized# docker exec $(docker ps -qf name=dovecot) doveconf -n | grep ssl
ssl = yes
ssl = yes
ssl_cert = </etc/ssl/mail/cert.pem
ssl_cipher_list = ALL:!ADH:!LOW:!SSLv2:!SSLv3:!EXP:!aNULL:!eNULL:!3DES:!MD5:!PSK:!DSS:!RC4:!SEED:!IDEA:+HIGH:+MEDIUM
ssl_dh = # hidden, use -P to show it
ssl_key = # hidden, use -P to show it
ssl_options = no_compression no_ticket
ssl_prefer_server_ciphers = yes
Tante Edit:
Ich hätte natürlich das komplette Workaround machen sollen. Bitte um Entschuldigung.
Ausgabe nun:
root@kn-mc01:/opt/mailcow-dockerized/data/conf/clamav# docker exec $(docker ps -qf name=postfix-mailcow) postconf -h tls_high_cipherlist
