# chasquid(1)

SMTP (email) server

## NAME

chasquid - SMTP (email) server

## SYNOPSIS

**chasquid** \[*options*...\]

## DESCRIPTION

chasquid is an SMTP (email) server with a focus on simplicity, security, and ease of operation.

It's written in Go, and distributed under the Apache license 2.0.

## OPTIONS

- **-config\_dir** *dir*

  configuration directory (default */etc/chasquid*)

- **-config\_overrides** *config*

  configuration values (in text protobuf format) to override the on-disk configuration with. This should only be needed in very specific cases for deployments where editing the configuration file is not feasible.

- **-alsologtostderr**

  also log to stderr, in addition to the file

- **-logfile** *file*

  file to log to (enables logtime)

- **-logtime**

  include the time when writing the log to stderr

- **-logtosyslog** *tag*

  log to syslog, with the given tag

- **-v** *level*

  verbosity level (1 = debug)

- **-version**

  show version and exit

## FILES

The daemon's configuration is by default in */etc/chasquid/*, and can be changed with the *-config\_dir* flag.

Inside that directory, the daemon expects the following structure:

- *chasquid.conf*

  Main config file, see [**chasquid.conf**(5)](/chasquid.conf/5.md).

- *domains/*

  Per-domain configuration.

- *domains/example.com/*

  Domain-specific configuration. Can be empty.

- *domains/example.com/users*

  User and password database for this domain.

- *domains/example.com/aliases*

  Aliases for the domain.

- *certs/*

  Certificates to use, one directory per pair.

- *certs/mx.example.com/*

  Certificates for this domain.

- *certs/mx.example.com/fullchain.pem*

  Certificate (full chain).

- *certs/mx.example.com/privkey.pem*

  Private key.

Note the *certs/* directory layout matches the one from certbot (client for Let's Encrypt CA), so you can just symlink *certs/* to */etc/letsencrypt/live*.

Make sure the user you use to run chasquid under ("mail" in the example config) can access the certificates and private keys.
