Plesk Obsidian introduced the Dynamic List View Mode and some of our customers are having problems understanding the new GUI.

It would be very helpful to configure the View Mode at the Service Plan level:
- Disable the possibility to change the View Mode
- Configure a default View Mode

Ability to change settings in the mail autodiscover - for example, to set the mail server that will be set in the mail client.

add HTTP/3

Implementing the new standard WebAuthn would be the best solution for 2FA.

As of now, feature with 178 votes is available in Plesk Onyx 17.9 Preview only: https://plesk.uservoice.com/forums/184549-feature-suggestions/suggestions/17924536-fail2ban-now-supports-ipv6-please-upgrade

It would be awesome to have this feature available on earlier versions of Plesk Onyx without the necessity to wait until Plesk Onyx 17.9 becomes stable.

Add mcrypt module to Plesk PHP 7.2 and newer.
For previous PHP versions it's included out of the box.

Mcrypt 1.0.2 natively supports PHP 7.2+ (https://pecl.php.net/package/mcrypt/1.0.2)

It's, for example, required by Prestashop 1.7.x, which is quite popular among Plesk users.

Allow the possibility to use a custom Hostname for Mail Auto Discovery.

For example:
Having a desginated ServerName for the Mail server requests and use the Auto Discovery to configure the Domains using that ServerName instead of using the Domain name.

Currently, management of additional Apache/nginx directives is available for Plesk Administrators only.

With Apache, it is possible for users to add custom directives via .htaccess file.

However, when running a Plesk server with nginx only hosting and a large number of customers, it takes a lot if time to configure nginx directives manually for each.

It is clear that additional Apache/nginx directives fields are hidden from Plesk users for security reasons, but it would be great to have an ability to enable this feature at your own risk.

By default the HTTP header 'x-powered-by: PleskLin' is added to HTTP responses.
And with PHP, even the version number is included: 'x-powered-by: PHP/7.3.5'

For security it is better to not give such information, as it may expose you are using outdated software with known vulnerabilities.
Currently it is possible to remove these headers, but it requires some manual actions using SSH (https://support.plesk.com/hc/en-us/articles/115000385274)

My suggestion is to create page to be able to manage such header additions for all websites and services.

Add the count of messages in the postfix mailq to Advanced Monitoring and Grafana. Then we have the option to get alerts if mailq goes up, in case of spam events!

For Plesk with non-English default language (Vietnamese, for example), notifications' content is still in English.

Please make "My Extensions" the default when I click on Extensions. After the server is set up, I don't ever need the Catalog.

We've had a similar suggestion before with insufficient information: https://plesk.uservoice.com/forums/184549-feature-suggestions/suggestions/34209229-add-php-handlers-restriction-per-service-plan

The idea is to be able to limit the number of available PHP handlers for selection at domain PHP settings.

This may be done at Service Plan X > Permissions.

Example: customer will be able to select only FPM server by Nginx.

This will allow the ability for more precise configuration.

Based on the support request.

To change default Thresholds for Server Health Monitor it was possible by upload custom template.

For "Advanced Monitoring" it's possible to change Thresholds only via GUI. That is not fast if you have many servers.

It would be have to make a feature to be able to manage "Advanced Monitoring" via command line or via templates. It

Service plans should be more granular, it should be possible to allow the customer to change the Document root without allowing them to manage the domain name, etc.

Basically the objective would be to have split the "Domains management" permission.

Add a possibility setting up SmarterMail via command-line interface to allow server administrators to perform mailserver setup faster and automate.

Mail authentication brute force attacks generate additional traffic.
It is counted as a part of POP3/IMAP traffic statistics in Plesk for Windows.
Please add functionality to recognize and ignore such normal traffic so that it does not forge POP3/IMAP statistics.

It would be very helpful to provide an option in Plesk GUI to configure the number of Plesk daily dumps (/var/lib/psa/dumps/mysql.daily.dump*) stored in the server due to the fact that only storing 8 dumps is not enough for our business standards.
