    It seems there is an error in this KB

    Item 5:

    # chmod 755 /usr/lib/plesk-9.0/postfix-local
    # chown popuser:popuser /usr/lib/plesk-9.0/postfix-local

    should be:

    # chmod 755 /usr/lib64/plesk-9.0/postfix-local
    # chown popuser:popuser /usr/lib64/plesk-9.0/postfix-local

    Thank you for bringing this to our attention. The article has been changed accordingly.

    Is the postfix-local for Debian 8 also usable for Ubuntu?

    Yes, it is, patch for Debian 8 is applicable for Ubuntu 16.04

    While it's nice to have a fix in place for 17.5.x, the micro updates of Plesk will eventually override the patched postfix-local, unless you block updates for the whole plesk-mail-pc-driver RPM package in the masin section of the /etc/yum.conf like so:

    exclude=plesk-mail-pc-driver*

    @Michel Otte,

    By blocking updates you may miss some important update.

    There is another way - create a cron task that will be executed after each Daily Maintenance task to re-apply the fix.

    The compilation failed of postsrsd on CentOS/CloudLinux 7. gcc also has to be installed for this to work so make sure it's installed:

     

    yum install -y unzip cmake gcc

    You can add something like this to your cronjob as a way to keep updates available but reset the fix if the postfix-local is overwritten.

    diff /root/postfix-local /usr/lib64/plesk-9.0/postfix-local || (cp -f /root/postfix-local /usr/lib64/plesk-9.0/postfix-local && service postfix restart)

    Hi!
    Thank you for sharing these hints.

    They may be useful for other Pleskians.
