Der Dovecot auf emma.ccchb.de akzeptiert die folgenden Cipher-Suites ohne PFS:

  • CAMELLIA128-SHA
  • AES128-SHA

Da hier keine allzu starke Kompatibilität notwendig ist, sollten die Cipher-Suites auf folgenden Wert konfiguriert werden:

ECDHE-ECDSA-AES128-GCM-SHA256:ECDHE-RSA-AES128-GCM-SHA256:ECDHE-ECDSA-AES256-GCM-SHA384:ECDHE-RSA-AES256-GCM-SHA384:ECDHE-ECDSA-CHACHA20-POLY1305:ECDHE-RSA-CHACHA20-POLY1305:DHE-RSA-AES128-GCM-SHA256:DHE-RSA-AES256-GCM-SHA384

(oder ähnlich)
