Now instead of renewing your Zimbra license annually, you can choose to purchase a perpetual license for Zimbra. This includes 1 year of support and updates for the first year. You may purchase support (including updates) for no more than 20% for every year thereafter.

The perpetual license is a nontransferable right to use the license for the number of mailboxes in the agreement. At the end of the 1st year from the date of issuance of the Zimbra license key and provided that support is still generally available, customer can pay a maintenance fee, no greater than (AMOUNT: total amount x 20%) per year, to continue to receive support, upgrades and updates or can continue to use the then current version for the number of license mailboxes in perpetuity for no additional fees.
