MAILBOO FREEWARE LICENSE AGREEMENT Version 1.0 - applies to MailBoo v11.0 and later releases that reference it Copyright (c) Lantrest LLC. All rights reserved. IMPORTANT - PLEASE READ. By downloading, installing, or using MailBoo (the "Software"), you agree to this agreement. If you do not agree, do not install or use the Software. 1. DEFINITIONS "Licensor" means Lantrest LLC, a limited liability company organized under the laws of the State of New Mexico, USA. "Software" means the MailBoo installer, the MailBoo application code, command-line tools, web interface, configuration templates, service definitions, scripts, documentation and artwork supplied by the Licensor, in the form in which the Licensor distributes them. "Third-Party Components" means all other programs that the Software installs, configures or interoperates with, such as Debian packages for Postfix, Dovecot, Rspamd, NSD, Unbound, Nginx, Roundcube, Radicale, BorgBackup, Certbot, Python libraries and similar. Third-Party Components are not part of the Software. "You" means the person or organisation that installs or uses the Software. 2. FREE OF CHARGE LICENSE GRANT The Licensor grants You a worldwide, non-exclusive, non-transferable, royalty-free license to: (a) download and install the Software on any number of servers that You own or operate; (b) use the Software for private, commercial, educational and non-profit purposes, including to provide mail and DNS services to Your own users and customers; (c) make backup copies of the Software for archival purposes; (d) redistribute the original, unmodified installer file, free of charge, provided that this license text and all copyright notices are kept intact and that You do not charge for the Software itself. The Software is provided free of charge. The Licensor may offer paid support or additional editions in the future; such offers will not retroactively remove Your rights under this agreement for versions You already received. 3. OWNERSHIP AND CLOSED SOURCE The Software is licensed, not sold. The Licensor retains all right, title and interest in the Software, including all intellectual property rights. The source code of the Software is proprietary and is not licensed under an open-source license. Even where parts of the Software are delivered in a human-readable form (for example scripts, configuration templates or interpreted code), this does not grant You any right to the source code beyond what this agreement expressly allows. 4. RESTRICTIONS Except as expressly permitted by this agreement or mandatory law, You may not: (a) modify, adapt, translate, or create derivative works of the Software; (b) redistribute, sublicense, sell, rent, lease or publicly host modified versions of the Software, or redistribute the Software together with a fee for the Software itself; (c) remove or alter copyright notices, trademarks, version information or this license; (d) publish the Software's code or use it to build a competing product; (e) use the Software to send unsolicited bulk email, to attack or disrupt other systems, or for any unlawful purpose. Nothing in this section limits rights that cannot be excluded by law, for example the right to observe, study and test the functioning of the Software while using it, or to decompile it to the extent strictly necessary for interoperability where mandatory law allows this. Changing configuration values through the Software's own interfaces and settings is permitted and is not a modification of the Software. 5. THIRD-PARTY COMPONENTS AND THEIR LICENSES The Software installs and configures Third-Party Components from the package sources of Your operating system (Debian). The Licensor does not distribute these components within the Software. Each Third-Party Component comes with its own license, which is installed together with that component (for example under /usr/share/doc//copyright on Debian systems) and which governs Your use of that component. Many Third-Party Components are licensed under open-source licenses (for example GPL, LGPL, BSD, MIT, Apache or similar). Nothing in this agreement restricts any right You have under such licenses, and this agreement does not apply to them. You are responsible for reading and complying with those licenses. Names of Third-Party Components are used only to describe compatibility and belong to their respective owners. MailBoo is not affiliated with or endorsed by their authors. 6. YOUR RESPONSIBILITIES You are solely responsible for the servers on which You install the Software, for the content and data You host with it (including email, contacts, calendars and DNS data), for keeping Your operating system and Third-Party Components updated, for keeping backups and backup passphrases safe, and for complying with all laws that apply to Your operation of a mail and DNS service, including data protection, telecommunications, anti-spam and retention laws. 7. NO WARRANTY TO THE FULLEST EXTENT PERMITTED BY LAW, THE SOFTWARE IS PROVIDED "AS IS" AND "AS AVAILABLE", FREE OF CHARGE, WITHOUT WARRANTY OF ANY KIND, EXPRESS OR IMPLIED, INCLUDING WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, NON-INFRINGEMENT, UNINTERRUPTED OPERATION, OR THAT EMAIL WILL BE DELIVERED OR THAT DNS, DNSSEC, TLS OR BACKUP FUNCTIONS WILL BE ERROR-FREE. Running mail, DNS and backup infrastructure carries inherent risk of data loss and service interruption, and You use the Software at Your own risk. 8. LIMITATION OF LIABILITY TO THE FULLEST EXTENT PERMITTED BY LAW, THE LICENSOR SHALL NOT BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL OR PUNITIVE DAMAGES, OR FOR LOSS OF DATA, PROFITS, REVENUE, REPUTATION OR BUSINESS INTERRUPTION, ARISING OUT OF OR IN CONNECTION WITH THE SOFTWARE, EVEN IF ADVISED OF THE POSSIBILITY OF SUCH DAMAGES. THE LICENSOR'S TOTAL LIABILITY FOR ANY CLAIM RELATING TO THE SOFTWARE IS LIMITED TO THE AMOUNT YOU PAID FOR THE SOFTWARE, WHICH IS ZERO. Nothing in this agreement excludes or limits liability that cannot be excluded or limited under applicable law, including liability for intent, gross negligence, or injury to life, body or health. 9. TERMINATION This agreement is effective until terminated. Your rights under it end automatically if You breach it. You may terminate it at any time by uninstalling the Software and deleting all copies. Sections 3, 4, 5, 7, 8 and 10 survive termination. Termination does not affect Your rights in Third-Party Components. 10. GENERAL (a) Governing law and jurisdiction: this agreement is governed by the laws of the State of New Mexico, USA, excluding its conflict-of-law rules. Courts located in New Mexico have jurisdiction, unless mandatory consumer-protection law of Your country of residence provides otherwise. (b) If any provision is held invalid, the remaining provisions remain in effect and the invalid provision will be replaced by a valid one that comes closest to its purpose.
