ActiveSync is a necessary tool for most businesses today as it allows them to have everything in one place and stream it automatically to every device they use. Users with mobile phones and tablets can easily sync their contacts, calendars, notes and emails via activesync and users with outlook and other mail clients can sync contacts, mail and perhaps notes.

Add a new Domain/Subdomain-Type "DynDNS", which redirects to a dynamic IP-Address like dyndns.org and similar sites including an api to sync the current ip address through url call.

It should be possible for the admin user to change his user login name. The name "admin" is not very secure, because it's easiert to hack via brute force. The hackers know, the name is "admin". If the user would be able to change his login name, it would increase the security of Plesk Panel.

Most of RBLS are checking the SMTP Banner and currently only the first domain name is being used. To reduce scamming or to prevent being blacklisted you should apply myhostname with the according domain name.

If the spam score is above the first threshhold, flag the message as spam or deliver it to Spam folder;

Reject it immediately (preferably during the SMTP session) or just discard if the score is above the second, higher threshold.

This way the customer would have more control over the anti-spam system, allowing much less true spam mail to enter the mailbox.

When I first saw the option of create DBs, I thought it was something like I'm suggesting. MongoDB, MariaDB, CouchDB, etc, etc. This will be super cool. :)

Many times I find that some subscriptions won't sync because they are locked. I'd really like to know why they are locked. So far, I've been able to unlock & sync with no noticeable changes. But I'm left wondering what caused the lock in the first place. And I'm afraid that I'll realize later something no longer works as expected.

enable email piping like in cPanel email forwarders to pipe to a script (osticket)

currently you can do it by IP/Port, but would like to be able to add firewall rules for things like string matching. A GUI would be ideal too.

In the "Service Plans" part, there is no option for setting the "Preferred domain" (seoRedirectDirection).
it is very inconvenience, because we need to set the "Preferred domain" (seoRedirectDirection) again and again after created the site.
It is possible to add this setting in the "Service Plans" part?

Add-on Modul CSF Firewall

Make each site able to run on its own IP.

If you would support this feature, please please tell us in the comments how you would use it - i.e. for SSL

Some of security configuration requires GeoIP detection. It also useful for tracing and should be easy as adding '--with-http-geoip-module' option to configure command for the package.

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).

In Migration Manager we need to provide a root user and password so that Plesk can access the source server. But providers like Amazon do not give you a root password by default. It would be great to have an option to upload the key file for the migration. Plesk could save it for future sessions, or offer to delete it after the migration.

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

I'll like to create a hosting that only use Nginx as webserver. Also I'll like to do this with Node.js, but I think it will not be approved.

Now you have two opportunities to set the spamfilter - server-wide or individual. It would be very handy if the admin or the customer could set the spamfilter for the whole subscription or/and for the whole domain.

1. Manage chroot environments from panel web interface
2. Add custom user scripts for install\remove chroot for domain
3. Sync files with system automatically, f.e. /etc/resolv.conf and other.
4. Link database servers socket into chroot for correct mysql psql command working.
