Display option summary.

All time-based command-line options and configuration file directives are subject to the syntax described in gromox(7), section "Duration specifications".

Configuration directives (gromox.cfg)¶

The following directives are recognized when reading from /etc/gromox/gromox.cfg, or when the -c option is used to specify a custom file:

daemons_fd_limit

In gromox-delivery, this is treated as an alias for lda_fd_limit.

lda_fd_limit

Request that the file descriptor table be at least this large. The magic value 0 indicates that the system default hard limit (rlim_max, cf. setrlimit(2)) should be used.
Default: 0

outgoing_smtp_url

See gromox.cfg(5):outgoing_smtp_url.

Configuration directives (delivery.cfg)¶

The following directives are recognized when reading from /etc/gromox/delivery.cfg, or when the -c option is used to specify a custom file:

admin_mailbox

An e-mail address where to send reports from the "net_failure" code component.
Default: (empty)

config_file_path

Colon-separated list of directories which will be scanned when locating further configuration files, especially those used by subcomponent instances. (For example, mysql_adaptor(4gx) would be directed to look at /etc/gromox/delivery/mysql_adaptor.cfg before /etc/gromox/mysql_adaptor.cfg.)
Default: /etc/gromox/delivery:/etc/gromox

data_file_path

Colon-separated list of directories in which static data files will be searched.
Default: /usr/share/gromox/delivery

dequeue_max_mem

Default: 1024M

dequeue_path

Default: /var/lib/gromox/queue

free_context_num

Default: 512

host_id

A unique identifier for this system. It is used for the DSN text of bounce messages. It is used as the value for the EHLO command if and when connecting to an SMTP service (e.g. inbox rules that do forwarding).
Default: (system hostname)

lda_log_file

Target for log messages here. Special values: "-" (stderr/syslog depending on parent PID) or "syslog" are recognized.
Default: - (auto)

lda_log_level

Maximum verbosity of logging. 1=crit, 2=error, 3=warn, 4=notice, 5=info, 6=debug.
Default: 4 (notice)

running_identity

An unprivileged user account to switch the process to after startup.
Default: gromox

work_threads_max

The number of threads that gromox-delivery may spawn to process incoming messages. This number must be less-or-equal to the exmdb_local(4) exmdb_connection_num directive to avoid rejection of messages in a message storm.
Default: 5

work_threads_min

Default: 1
