Name¶

- 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".
Plugins¶
The delivery daemon can be extended by a number of plugins. In Gromox, their filenames begin with libmtahook_.
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
- The SMTP server to use for outgoing mails. To use the local maildrop
queue, set the value to sendmail://localhost. smtp:// is
unqueued(!), and if the SMTP server is offline, submissions cannot be
carried out.
Default: smtp://%3a%3a1:25/
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 in which further configuration files,
especially those used by plugin instances, will be searched.
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
