.IX Header "DESCRIPTION"
chasquid is an \s-1SMTP\s0 (email) server with a focus on simplicity, security, and
ease of operation.
.PP
It's written in Go, and distributed under the Apache license 2.0.
.SH "OPTIONS"
.IX Header "OPTIONS"
.IP "\fB\-config_dir\fR \fIdir\fR" 8
.IX Item "-config_dir dir"
configuration directory (default \fI/etc/chasquid\fR)
.IP "\fB\-config_overrides\fR \fIconfig\fR" 8
.IX Item "-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.
.IP "\fB\-alsologtostderr\fR" 8
.IX Item "-alsologtostderr"
also log to stderr, in addition to the file
.IP "\fB\-logfile\fR \fIfile\fR" 8
.IX Item "-logfile file"
file to log to (enables logtime)
.IP "\fB\-logtime\fR" 8
.IX Item "-logtime"
include the time when writing the log to stderr
.IP "\fB\-logtosyslog\fR \fItag\fR" 8
.IX Item "-logtosyslog tag"
log to syslog, with the given tag
.IP "\fB\-v\fR \fIlevel\fR" 8
.IX Item "-v level"
verbosity level (1 = debug)
.IP "\fB\-version\fR" 8
.IX Item "-version"
show version and exit
.SH "FILES"
.IX Header "FILES"
The daemon's configuration is by default in \fI/etc/chasquid/\fR, and can be
changed with the \fI\-config_dir\fR flag.
.PP
Inside that directory, the daemon expects the following structure:
.IP "\fIchasquid.conf\fR" 8
.IX Item "chasquid.conf"
Main config file, see \fBchasquid.conf\fR\|(5).
.IP "\fIdomains/\fR" 8
.IX Item "domains/"
Per-domain configuration.
.IP "\fIdomains/example.com/\fR" 8
.IX Item "domains/example.com/"
Domain-specific configuration. Can be empty.
.IP "\fIdomains/example.com/users\fR" 8
.IX Item "domains/example.com/users"
User and password database for this domain.
.IP "\fIdomains/example.com/aliases\fR" 8
.IX Item "domains/example.com/aliases"
Aliases for the domain.
.IP "\fIcerts/\fR" 8
.IX Item "certs/"
Certificates to use, one directory per pair.
.IP "\fIcerts/mx.example.com/\fR" 8
.IX Item "certs/mx.example.com/"
Certificates for this domain.
.IP "\fIcerts/mx.example.com/fullchain.pem\fR" 8
.IX Item "certs/mx.example.com/fullchain.pem"
Certificate (full chain).
.IP "\fIcerts/mx.example.com/privkey.pem\fR" 8
.IX Item "certs/mx.example.com/privkey.pem"
Private key.
.PP
Note the \fIcerts/\fR directory layout matches the one from certbot (client for
Let's Encrypt \s-1CA\s0), so you can just symlink \fIcerts/\fR to
\&\fI/etc/letsencrypt/live\fR.
.PP
Make sure the user you use to run chasquid under (\*(L"mail\*(R" in the example
config) can access the certificates and private keys.
.SH "CONTACT"
.IX Header "CONTACT"
Main website <https://blitiri.com.ar/p/chasquid>.
