    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.
