postfix SSL_accept error from localhost

[uek]

Hallo,

ich habe folgendes Problem mit meinem Mailserver (Postfix/Dovecot)

Für IMAP/OPO3 verwende ich STARtTLS für smtp SSL/TLS
sntp funktioniert imap/pop nichrt aufgrund eines SSL-accept error vom server:
mail.err

Code: Alles auswählen

Was muss ich wie ändern damit das SSL-Zertifikat akzeptiert und die Konfiguration gelesen wird.

... imap dovecot: pop3-login: ... Error reading configuration: read(/var/run/dovecot/config)

hier srw------- root:root.

Der Haupt-dovecot läuft als root, dito dovecot/log,
dovecot/anvil als dovecot,
dovecot/imap (hier) als vmail.
