E-mail filtering is a crucial part of any modern mail server and, for this reason, we're excited to announce the addition of Milter support to the Stalwart Mail Server. This update, driven by user feedback, allows the integration of both new and old Milter filters, supporting versions 2 and 6, which expands the server's capabilities in inspecting, filtering, or modifying emails during processing.

A milter, or "mail filter", is an extension to mail servers based on the Sendmail protocol. Milters allow third-party software to access mail messages as they are being processed in order to filter, modify, or annotate them. By using Milters, a mail server can utilize a variety of functionalities such as spam filtering, virus scanning, and other types of mail processing, beyond what is built into the mail server itself. Milters operate at the SMTP protocol level, which means they have access to both the SMTP envelope and the message contents.

This new feature not only responds to our users' needs but also ensures that Stalwart can work seamlessly with any existing setup. Whether you are seeking better spam protection, antivirus measures, or implementing specific processing rules, milter filtering has got you covered.

We’re excited to announce that Stalwart Labs has received a grant from the NGI0 Entrust Fund. This fund, established by NLnet with financial support from the European Commission’s Next Generation Internet programme, aims to support the development of innovative and secure technologies for the internet of the future.

The purpose of the grant is to support the completion of the development of the Stalwart Mail server, an open-source mail server written in Rust that is designed to be simple to run, but at the same time, extremely secure, robust, and focused on privacy. The funds from this grant will cover the development of several new features that will make the Stalwart Mail server even more useful and user-friendly.

The features that the Stalwart Labs team will develop with the support of the NGI0 Entrust Fund include Stalwart SMTP, HTTP Listener / JSON Parsing refactoring, Store Refactoring, MinIO/S3 blob storage, Quota support, External authentication support, Catch-all addresses and aliases, JMAP Quota, JMAP Blob, JMAP Contacts, JMAP Calendars, JMAP Tasks, JMAP MDN, and the integration of SMTP, JMAP, and IMAP. Additionally, the grant will also cover security auditing, ensuring that the Stalwart Mail Server is as secure and reliable as possible.

With the completion of these features, the Stalwart Mail server will become an even more powerful tool for individuals and organizations looking for a secure and private email solution. We look forward to seeing the impact that this innovative technology will have on the future of email and online communication.

We are grateful to NLnet, and the European Commission’s Next Generation Internet programme for their support in the development of the Stalwart Mail server. We believe that this grant will enable us to make significant progress in the development of this important open-source project, and we look forward to sharing our progress with the community in the coming months.
