Silver Project

A professional, self-hosted email solution that puts you in complete control.


Features Overview

Feature Description Status
Unmatched Cost Efficiency – Free! Imagine your organization has 1,000 employees. How much are you spending on email services? With popular providers like Google Workspace ($6-7/user/month) or Microsoft 365 ($12.50/user/month), you're spending $72,000-150,000 per year.1,2 Now imagine cutting that cost to minimal infrastructure expenses—while still providing a professional, secure, role-based email system. With Silver Project, that's reality. Affordable, powerful, and fully under your control. Completed
Lightweight Infrastructure Requirements Do you need powerful CPUs or huge amounts of memory? No. Silver Project is extremely lightweight and optimized to run on minimal infrastructure without compromising performance or reliability. Lower costs, easier deployment, less maintenance—while delivering a full-featured, professional email experience. Approved
Professional Role-Based Email Identity When you receive an email from anura@gmail.com, do you really remember who sent it? Personal emails lack organizational authority. Now imagine using role-based addresses like ceo@yourcompany.com, support@yourcompany.com, or sales@yourcompany.com. Recipients immediately see the credibility and authority behind the message. It's not just an email—it's a representation of your organization. In Progress
Complete Data Ownership & Security When you send sensitive information via Gmail or other public providers, do you know where that data goes? Can you control who accesses it? With Silver Project, you can. Your data stays exactly where you decide. You control the storage, access, infrastructure, and entire security lifecycle. Full transparency, full ownership, full peace of mind. Completed
Reliable & Disaster-Proof Backups What happens if your server crashes, burns, or gets stolen? With Silver Project's reliable backup strategy, your data remains safe and protected. Configure backups according to your needs—your information stays intact even in worst-case scenarios. Not Started
Built-In Spam & Virus Protection Do you need special firewalls or external tools? No. Silver Project includes enterprise-grade protection: advanced spam filtering, malware scanning, and security controls—all built in. No extra firewalls, no additional appliances, no hidden costs. Complete, integrated protection from day one. Completed
Effortless Group Emailing Tired of typing long CC lists? Organize people into groups and send emails to a single group address—everyone receives it instantly. Simple, efficient, and eliminates the hassle of manually adding multiple recipients every time. Not Started
Identity Provider (IdP) Separation Already using an Identity Provider such as Thunder, Keycloak, Azure AD, or Okta? Our email system integrates seamlessly with your existing IdP, allowing you to manage email accounts using the same identities, roles, and access policies—eliminating duplication and simplifying user management. Not Started
Email Workflow Automation Emails sent to organizational addresses can follow predefined workflows, where authorized users take actions, apply labels, and move the email through different stages. Senders can track the status of their requests, bringing transparency and structure to email-based processes. Not Started
Native High-Performance Email Client Our native email client supports both IMAP and JMAP, a modern protocol designed for faster synchronization and efficient email processing. JMAP uses JSON and HTTP to enable batch requests, reducing network roundtrips and improving sync speed—especially on mobile networks and limited bandwidth connections.3,4,5 This ensures a responsive, future-ready email experience across devices and networks. Not Started
Email Expiration & Lifecycle Control Senders can define expiration dates for emails, after which messages are automatically marked as expired and governed by retention policies. This helps manage sensitive or time-bound communications more securely. Not Started
Attachment Storage in Object Storage Attachments are stored separately in object storage while emails retain only references, significantly reducing mailbox size and storage costs. Object storage excels at handling large volumes of unstructured data like email attachments, offering unlimited scalability and lower costs compared to traditional file storage.6,7 This approach improves performance, scalability, and backup efficiency.
