    The issue described in this article caused by incorrect SELinux contexts.
    SELinux is not installed in Ubuntu by default, and it is not supported by Plesk on Ubuntu servers. Most likely you are experiencing another issue.

    I suggest checking if all mail-related services are running in Tools & Settings > Services Management and reviewing /var/log/maillog file for additional symptoms to use it for searching the relevant article.

    If the issue still will not be resolved, contact regular Plesk support for further assistance.

    Seit den Wartungsarbeiten am 28.01. seitens Strato funktionieren alle E - Mail-Konten nicht mehr.
    Mailservereinstellungen in Plesk lassen sich nicht mehr ÄNDERN.
    Strato Hotline - zuckt mit den Schultern und meint das ist nicht Unsere Schuld, der Grund des Mailserverausfalls Liegt nicht bei sich, nicht einer unseren speziellen Wartungsarbeiten.
    Komisch ist nur, that Seithers die E - Mail nicht mehr funktioniert. Strato Meint Fehler liege bei Plesk der.

    Wer kann hier helfen?
    ystem: Ubuntu 16.04.5 LTS
    Mail: postfix 3.1.0-3ubuntu0.3

    Fehlermeldung beim Speichern der Mailserver-Settings in Plesk (ohne Änderung)

    Hello Jan,

    I will answer to you in English. I have an assumption that you faced an issue described in this article - After server reboot Fail2Ban unable to start and Mail forwarding for mailbox cannot be enabled: Unable to open file /run/lock/files/. Please check if it helps you.
