• The new Python extension is now available. It allows customers to deploy and manage WSGI-based Python applications on their websites directly from Plesk.
  • Debian 11 has reached its end-of-life (vendor EOL date - August 31, 2026). Plesk Obsidian 18.0.81 is the last release to support it.
    If you are running Plesk Obsidian on Debian 11, we recommend you upgrade those servers to Debian 12 using our dist-upgrade tool.
  • We plan to deprecate and remove the support for XML RPC protocol versions earlier than 1.6.9.1 in Plesk Obsidian 18.0.82. We strongly recommend that you update all existing integrations using earlier versions of the XML RPC protocol to comply with the version 1.6.9.1 specification.

After every upgrade I have to perform the following system tweaks. I wish they were sorted in the Plesk upgrades.

1) To be able to view PDF's in Horde

1.file: /home/httpd/vhosts/webmail/horde/lib/Horde.php
Change session_cache_limiter($conf['cache_limiter']);
to //session_cache_limiter($conf['cache_limiter']);

Change /home/httpd/vhosts/webmail/horde/imp/view.php these strings:
if ($conf['compress_pages'] && ($actionID != SAVE_MESSAGE) &&
($actionID != DOWNLOAD_ATTACH)) {
ob_start('ob_gzhandler');
}

to
Chnage /home/httpd/vhosts/webmail/horde/imp/view.php these strings:
/*
if ($conf['compress_pages'] && ($actionID != SAVE_MESSAGE) &&
($actionID != DOWNLOAD_ATTACH)) {
ob_start('ob_gzhandler');
}
*/

2) To be able to view html emails in horde
/home/httpd/vhosts/webmail/horde/imp/config/mime_drivers.php
change $mime_drivers['imp']['html']['inline'] = false;
to chnage $mime_drivers['imp']['html']['inline'] = true;

3) To chnage the name of Horde to Webmail
/home/httpd/vhosts/webmail/horde/config/registry.php
Change 'name' =>Horde
to 'name' =>Webmail

4) To speed up the sending of email
/etc/xinetd.d/smtp_psa
change server_args = /var/qmail/bin/relaylock......
to -Rt0 /var/qmail/bin/relaylock......
then run service xinetd restart
