The PLESK 30 Domain license that comes by default with our Managed Servers allows you to manage/add up to 29 domains on your server.  One license is used for the server name itself.. ie server4.3essentials.com...etc.

Some other features that are not included are:

1.  The ability to create MS SQL Databases and manage them from within PLESK

2.  The ability to configure SPAM Filter settings for your mailboxes.

If you require these two features, then you will need the SwSoft PLESK PowerPak license.  Contact our Sales department for current pricing for this add-on.

The default mail server that comes with PLESK is MailEnable Standard Version.  Visit http://www.mailenable.com for more information.

3Essentials does support SmarterMail as an upgrade.  Contact 3Essentials Sales to obtain pricing information on SmarterMail.  You can find more information on SmarterMail at http://www.smartertools.com
