NAME
|
|
----
|
|
cdist-type__dma - Setup the DragonFly Mail Agent as the MTA.
|
|
|
|
|
|
DESCRIPTION
|
|
-----------
|
|
This (singleton) type uses DMA, a small Mail Transport Agent (MTA), to accept
|
|
mails from locally installed Mail User Agents (MUA) and either deliver the mails
|
|
to a remote smart host for delivery or communicate with remote SMTP servers
|
|
directly.
|
|
|
|
|
|
REQUIRED PARAMETERS
|
|
-------------------
|
|
None.
|
|
|
|
|
|
BOOLEAN PARAMETERS
|
|
------------------
|
|
defer
|
|
If enabled, mail will not be sent immediately, but stored in a queue.
|
|
To flush the queue and send the mails, ```dma -q`` has to be run
|
|
periodically (e.g. using a cron job.)
|
|
This type does not manage such a cron job, but some operating systems ship
|
|
such a cron job with the package.
|
|
fullbounce
|
|
Enable if bounce messages should include the complete original message,
|
|
not just the headers.
|
|
nullclient
|
|
Enable to bypass aliases and local delivery, and instead forward all mails
|
|
to the defined ``--smarthost``.
|
|
send-test-mail
|
|
If set, this type will send a test email to root after setup, to check if
|
|
the configured settings work.
|
|
|
|
|
|
OPTIONAL PARAMETERS
|
|
-------------------
|
|
mailname
|
|
If present, this will be the hostname used to identify this host and the
|
|
remote part of the sender addresses.
|
|
If not defined, it defaults to ``/etc/mailname`` on Debian derivatives and
|
|
to ``__target_fqdn`` otherwise.
|
|
See `dma(8)` for more information.
|
|
|
|
Note: on Debian derivatives the ``/etc/mailname`` file should be updated
|
|
instead of using this parameter.
|
|
masquerade
|
|
Masquerade the envelope-from addresses with this address/hostname.
|
|
Use this setting if mails are not accepted by destination mail servers
|
|
because your sender domain is invalid.
|
|
This option can be used multiple times.
|
|
For more information see the `dma(8)` man page.
|
|
port
|
|
The port on which to deliver email.
|
|
If not provided, a sensible default port will be used based on the
|
|
``--security`` argument.
|
|
security
|
|
Configures whether and how DMA should use secure connections.
|
|
|
|
ssl/tls
|
|
Enable TLS/SSL secured transfer.
|
|
starttls
|
|
Use STARTTLS to establish a secure connection.
|
|
opportunistic (default)
|
|
Will try to establish a secure connection using STARTTLS, but allow
|
|
unencrypted transfer if STARTTLS fails.
|
|
Most useful when dma is used without a smarthost, delivering remote
|
|
messages directly to the outside mail exchangers.
|
|
insecure
|
|
allow plain text SMTP login over an insecure connection.
|
|
Should really *not* be used anymore!
|
|
smarthost
|
|
The mail server used to send email.
|
|
It must be configured to act as a relay for the host being configured by
|
|
this type so that mail can be sent to users non-local to the smarthost.
|
|
|
|
|
|
EXAMPLES
|
|
--------
|
|
|
|
.. code-block:: sh
|
|
|
|
# Install DMA and use the smarthost mx1.domain.tld to send mail.
|
|
__dma --smarthost mx1.domain.tld --send-test-mail
|
|
|
|
# Install DMA in a default configuration.
