Can I use a new license on an older installation? Yes! Our licenses are backwards compatible, meaning a newer license can be used on any older version of the software as long as Maintenance and Support is active for the license.

However, you cannot go beyond that version without first renewing or reinstating Maintenance and Support. If you do not have active Maintenance and Support, you DO have the ability to install any version up to when the Maintenance and Support expired for that license. Can I install any version? If you're using the free edition, yes! If you have a licensed installation, and active Maintenance and Support, you can install any current or legacy version, so you can re-install your existing version or upgrade to the most current Build.

This includes bug fixes, patches, updates and new features. What about bug fixes and patches? Customers with active Maintenance and Support for their licenses have access to ALL new builds of our products. Simply contact our sales department by emailing During business hours you can also start a live chat or call us at 87. If you need more mailboxes or want to test using multiple domains, we'd be happy to provide you with a 30-day trial. Once SmarterMail finishes installing, it will run as the Free Edition! It's a fully-functional product that has some Enterprise features built-in. Then, when asked for a License Key during installation, leave that area blank. How can I "Try for Free"? If you don't have a license key but want to try SmarterMail on a single domain for up to 10 mailboxes, you can simply download SmarterMail.
