One software license is required per machine.

Single Server License is based on the maximum total number of users. Number of domain names is not limited.

Includes 1st year of standard support and updates

Under the Single Server License, the software may be installed on your web site(s) or internal network(s) without any limitation as to the number of domain names. Additionally, developers of internal software systems may modify our source code to integrate WebMail Pro software with your other applications. If you are an Independent Software Vendor, you may also procure this license in order to integrate WebMail Pro software with your larger and more complex application, but only if such application would be offered strictly as a SaaS hosted solution. ISVs need to keep in mind that redistribution of WebMail Pro software is not allowed without special permission. Please contact us prior to purchasing a license if you think that you may require special licensing arrangements.
