Mailserver Dovecot + Postfix / -Admin-Authentifizierung fehlgeschlagen

jeder. Ich habe in einigen Tagen nach dem Fehler gesucht ..

Wenn ich mein Webmail über Imap / Smtp mit meinem E-Mail-Server verbinden möchte, habe ich folgende Fehlermeldung erhalten: "Authentifizierung fehlgeschlagen". Wenn Sie weitere Informationen benötigen, fragen Sie bitte nach. Kannst du mein Konfigurationsproblem finden?

Mit freundlichen Grüßen.

Fehlermeldung:
