Actually it's possible to show deferred messages headers in : Tools and settings > mail server settings > mail queue

It would be very useful if it's possible to show the reason why the message is deffered or stuck in the queue (/var/spool/postfix/defer).

Being able to modify the subject in notification emails.

Add two-factor-auth for YubiKey.

There is relatively new anti-spam tool - Rspamd. I think, it worth to be integrated with Plesk as an alternative to SpamAssassin. It shows better performance as the author says here http://rspamd.com/misc/2016/03/03/rspamd-performance.html

Please add PHP Composer to chrooted Environments.
Many Customers Need PHP Composer to install various scripts, cms Systems and libaries.

A current big Problem is the new typo-neos System - you must use Composer to install at sources correctly

A other Problem are PHP API's and Libaries like Payment Companies like PAYMILL etc..

It'd be awesome if we can get support for powerdns support instead of bind9.

It would be much better if server-wide and per-mailbox options were available in Plesk to add SpamAssassin rules.

SpamAssassin can be configured by the command line, but this is difficult for many of us.

Hi, To restore a single file from FTP repository, it required whole full to download and then restore required data. Which consumes lot of time. Please try to work this backup/restore operation like other backup application where we can select required data and it get easily download without time consuming.

Also the backup tab should give option like dayswise full, incremental backup. Start and stop backup schedule, etc...

We the providers could generate a temp password (customer asks for a reset), and after the first login screen, plesk will force ask from the client to change our temp password.

Possibility to configure separate relay Server for specific Domains., or local / direct delivery.This is asked by customers very often in past.
Usefull if you have a smarthost for outgoing and incomming mails (Anti-Spam, -Malware, etc.).

I want to be able to set the recipient_delimiter. But, currently, any customizations to main.cf get overwritten.

There is an spam filtering option to "Move to spam folder XXXX" on Linux, but not on Windows (Plesk 11+).

Unfortunately, horde doesn't work so well and every time when a message with broken header arrives, horde displays "Invalid Address" and no subject to all inbox messages. The described fix in https://kb.plesk.com/en/121175 doesn't work in this cases, forcing us to find the broken message manually (or scripting something to do the dirty job).

This feature should exists in Windows env as in Linux.

I would love to use exchange server 2013 while using plesk panel. Exchange server is by far the most superior email server for windows and would be a great addition to plesk panel.

I believe that there is also an open API or an easy way to send commands which would make it a lot easier to integrate with.

Currently CloudFlare ServerShield is implemented using partial (CNAME) setup. What is the point in a partial setup when you can benefit from full DNS? You get anycast DNS with CloudFlare on full DNS.

The new security option for plesk 12 is Fail2Ban, but it is only for Linux version.

There is an opensorce for windows.
