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.

Add two-factor-auth for YubiKey.

In light of the Snowden fallout, I hope that Plesk will add support for Mailpile (http://www.mailpile.is) or something similar for secure e-mail.

Can we have an extension that allows backup to Microsoft OneDrive. Similar to the Dropbox extension that is currently available

Support MongoDB as a database in for websites

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).

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

There is an opensorce for windows.

I suggest to Parallels Team include this.

Ability to renew a subscription based on the subscription plan's configured subscription expiry date.

So if a subscription expires in ten days from now and it's subscription plan is set to expire in one year, I would like to be able to click a Renew button to extend the subscription with one more expiry unit (1 year in this case, 2 years if the subscription plan would have been set to expire every two years).

Also show renewal date in the list and sort by renewal date

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.

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

It would be nice to have an external SMTP (smarthost) ability for a per-domain basis (most mail services have this)

We use this for external scanning, data leak prevention and more.

Can this be be done?

Ask user to change password at next login screen after reset.
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.

The ability to empty a users emailbox without deleting the account and recreating would be great.

At some time you closed the request "fail2ban for IPv6" stating that fail2ban does not support it. That was no doubt correct at the time - but now it does, see https://github.com/fail2ban/fail2ban/tree/0.10

I'm seeing a lot of warnings in the fail2ban log on my dual stack servers, like this:

66:1000:b01c:10ab:0:1: [Errno -9] Address family for hostname not supported

and my log checking software is complaining to me about the overly long fail2ban log.

Thanks! Tim.

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

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..
