SMTP server
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 authentication, strong
transport security through DANE, MTA-STS and SMTP TLS reporting, and
offers great flexibility and customization thanks to its dynamic
configuration rules and native support for Sieve scripts.
