**Stalwart SMTP** is a modern SMTP server developed in Rust with a focus on security, speed, and extensive configurability.
It features built-in DMARC, DKIM, SPF and ARC support for message and sender authentication, strong transport security through DANE, MTA-STS, SMTP TLS reporting and offers great flexibility and customization thanks to its configurable rules and native support for Sieve scripts.
Key features:
- Sender and Message Authentication:
- Domain-based Message Authentication, Reporting, and Conformance (**DMARC**) verification and failure/aggregate reporting.
- DomainKeys Identified Mail (**DKIM**) verification, signing and failure reporting.
- Sender Policy Framework (**SPF**) policy evaluation and failure reporting.
- Authenticated Received Chain (**ARC**) verification and sealing.
- Reverse IP (**iprev**) validation.
- Strong Transport Security:
- DNS-Based Authentication of Named Entities (**DANE**) Transport Layer Security.
- SMTP MTA Strict Transport Security (**MTA-STS**).
- SMTP TLS Reporting (**TLSRPT**) delivery and analysis.
- Inbound Filtering and Throttling:
- Sieve scripting language with support for all [registered extensions](https://www.iana.org/assignments/sieve-extensions/sieve-extensions.xhtml).
- Filtering, modification and removal of MIME parts or headers.
- DNS block lists (**DNSBL**).
- Greylisting.
- Inbound concurrency and rate limiting.
- Integration with external content filtering systems such as SpamAssassin and ClamAV.
- Flexible Queues:
- Unlimited virtual queues.
- Delayed delivery with `FUTURERELEASE` and `DELIVERBY` extensions support.
- Priority delivery with `MT-PRIORITY` extension support.
- Quotas.
- Outbound throttling.
- Custom routing rules.
- Logging and Reporting:
- Detailed logging of SMTP transactions and events, including delivery attempts, errors, and policy violations.
- Integration with **OpenTelemetry** to enable monitoring, tracing, and performance analysis of SMTP server operations.
- Automatic analysis of incoming DMARC/TLS aggregate reports, DMARC/DKIM/SPF authentication failure reports as well as abuse reports.
- And more:
- SASL authentication.
- PostgreSQL, MySQL, MSSQL and SQLite support.
- Granular configuration rules.
- REST API for management.
- Memory safe (thanks to Rust).
