SYNOPSIS

       chasquid.conf(5) is chasquid(1)'s main configuration file.

DESCRIPTION

       The file is in protocol buffers' text format.

       Comments start with "#". Empty lines are allowed.  Values are of the form "key: value". Values can be
       strings (quoted), integers, or booleans ("true" or "false").

       Some values might be repeated, for example the listening addresses.

OPTIONS

       hostname (string):
               Default hostname to use when saying hello. This is used to say hello to clients, for aesthetic
               purposes. Default: the system's hostname.

       max_data_size_mb (int):
               Maximum email size, in megabytes. Default: 50.

       smtp_address (repeated string):
               Addresses to listen on for SMTP (usually port 25). Default: "systemd", which means systemd passes
               sockets to us. systemd sockets must be named with FileDescriptorName=smtp.

       submission_address (repeated string):
               Addresses to listen on for submission (usually port 587). Default: "systemd", which means systemd
               passes sockets to us. systemd sockets must be named with FileDescriptorName=submission.

       submission_over_tls_address (repeated string):
               Addresses to listen on for submission-over-TLS (usually port 465). Default: "systemd", which
               means systemd passes sockets to us. systemd sockets must be named with
               FileDescriptorName=submission_tls.

       monitoring_address (string):
               Address for the monitoring HTTP server. Do NOT expose this to the public internet. Default: no
               monitoring server.

       mail_delivery_agent_bin (string):
               Mail delivery agent (MDA, also known as LDA) to use. This should point to the binary to use to
               deliver email to local users. The content of the email will be passed via stdin. If it exits
               unsuccessfully, we assume the mail was not delivered. Default: maildrop.

       mail_delivery_agent_args (repeated string):
               Command line arguments for the mail delivery agent. One per argument.  Some replacements will be
               done.

               On an email sent from marsnik@mars to venera@venus:

                   %from%        -> from address (marsnik@mars)
                   %from_user%   -> from user (marsnik)
                   %from_domain% -> from domain (mars)
                   %to%          -> to address (venera@venus)
                   %to_user%     -> to user (venera)
                   %to_domain%   -> to domain (venus)

               Default: "-f", "%from%", "-d", "%to_user%"  (adequate for procmail and maildrop).

       data_dir (string):
               Directory where we store our persistent data. Default: /var/lib/chasquid.

       suffix_separators (string):
               Suffix separator, to perform suffix removal of local users.  For example, if you set this to
               "-+", email to local user "user-blah" and "user+blah" will be delivered to "user".  Including "+"
               is strongly encouraged, as it is assumed for email forwarding.  Default: "+".

       drop_characters (string):
               Characters to drop from the user part on local emails.  For example, if you set this to "._",
               email to local user "u.se_r" will be delivered to "user".  Default: ".".

       mail_log_path (string):
               Path where to write the mail log to.  If "<syslog>", log using the syslog (at "MAIL|INFO"
               priority).  Default: "<syslog>".

       dovecot_auth (bool):
               Enable dovecot authentication. If true, users that are not found in chasquid's databases will be
               authenticated via dovecot.  Default: "false".

               The path to dovecot's auth sockets is autodetected, but can be manually overridden using the
               "dovecot_userdb_path" and "dovecot_client_path" if needed.
