# chasquid
|
|
|
|
[chasquid](https://blitiri.com.ar/p/chasquid) is an SMTP (email) server.
|
|
|
|
It aims to be easy to configure and maintain for a small mail server, at the
|
|
expense of flexibility and functionality.
|
|
|
|
It's written in [Go](https://golang.org), and distributed under the
|
|
[Apache license 2.0](http://en.wikipedia.org/wiki/Apache_License).

## Features
|
|
|
|
* Easy to configure.
|
|
* Hard to mis-configure in ways that are harmful or insecure (e.g. no open
|
|
relay, or clear-text authentication).
|
|
* Tracking of per-domain TLS support, prevents connection downgrading.
|
|
* International usernames ([SMTPUTF8]) and domain names ([IDNA]).
|
|
* Hooks for easy integration with greylisting, anti-virus and anti-spam.
|
|
* Multiple domains, with per-domain user database and aliases.
|
|
* Multiple TLS certificates.
|
|
* Suffix dropping (`user+something@domain` → `user@domain`).
|
|
* Easy integration with [Let's Encrypt].
|
|
* [SPF] checking.
|
|
* Monitoring HTTP server, with exported variables and tracing to help
|
|
debugging.
|
|
* Supports using [Dovecot] for authentication (experimental).
|
|
|
|
The following are intentionally *not* implemented:
|
|
|
|
* Custom email routing.
|
|
* [DKIM]/[DMARC] checking (although the post-data hook can be used for it).

## Status
|
|
|
|
chasquid is in beta.
|
|
|
|
It's functional and has had some production exposure, but some things may
|
|
still change in backwards-incompatible way, including the configuration format.
|
|
It should be rare and will be avoided if possible.
