.SH FILES
.IX Header "FILES"
The daemon\*(Aqs 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 (can also be named \fIkey.pem\fR).
.PP
Note the \fIcerts/\fR directory layout matches the one from certbot (client for
Let\*(Aqs Encrypt CA), so you can just symlink \fIcerts/\fR to
\&\fI/etc/letsencrypt/live\fR.
The layout from the NixOS ACME module (\fI/var/lib/acme\fR) is also supported.
.PP
Make sure the user you use to run chasquid under ("mail" in the example
config) can access the certificates and private keys.
