Nextcloud 18.02 nach Update App Email 1.14, Error

An Alle,
nach dem Update von Mail auf 1.14 habe ich keine Verbindung mehr zu meinem IMAP und SMTP Server. Folgende Fehlermeldung:

Meine Beiden Server sind natürlich Online. Die App Raunloop greift ganz normal darauf zu aus Nextcloud
Auch eine Verbindung ohne TLS geht nicht.

Mein Imap Server sagt folgendes:
ar 24 15:13:06 s4slave dovecot: imap-login: Disconnected (no auth attempts in 0 secs): user=<>, rip=192.168.135.34, lip=192.168.135.253, TLS handshaking: SSL_accept() failed: error:14094418:SSL routines:SSL3_READ_BYTES:tlsv1 alert unknown ca: SSL alert number 48, session=

Hast Du auf dem Server auch das CA-Zertifikat installiert welches verwendet wurde um das E-Mail-Serverzertifikats zu signieren?

Mit dem aktuelle Release wurden Änderungen am TLS-Handling vorgenommen. Vielleicht kannst Du ja auch den angegebenen Workaround bei Dir verwenden:

Vielen dank für den Tipp, Horde funktioniert jetzt wieder aber ein Fehler bleibt, den schlepp ich schon seit dem letzten Update herum. Gibt es dafür endlich eine Lösung. Ich denke es hat vielleicht etwas mit der PHP-FPM Version 7.3 zu tun,
