Forked from the smtpbis library.
Extensible SMTP server library
Built on top of rustyknife and tokio for native performance.
The ESMTP extensions that affect the socket layer are directly implemented in the base server. Extensions such as DSN that merely attributes are implemented via the Handler interface.
Features:
- SMTPUTF8 support
- CHUNKING support
- Pluggable STARTTLS support
