dma - DragonFly Mail Agent  


[-DiOt [-A mode ] ] [-b mode ] [-f sender ] [-L tag ] [-o option ] [-r sender ] [-q [arg ] ] [recipient ... ]  


is a small Mail Transport Agent (MTA), designed for home and office use. It accepts mails from locally installed Mail User Agents (MUA) and delivers the mails either locally or to a remote destination. Remote delivery includes several features like TLS/SSL support and SMTP authentication.

is not intended as a replacement for real, big MTAs like sendmail(8) or postfix(1). Consequently, does not listen on port 25 for incoming connections.

The options are as follows:

-A mode
-Ac acts as a compatibility option for sendmail.
-b mode

List all mails currently stored in the mail queue.
Queue the mail, but don't attempt to deliver it. See also the `DEFER' config file setting below.

All other mode s are are ignored.

Don't run in the background. Useful for debugging.
-f sender
Set sender address to sender
Ignore dots alone on lines by themselves in incoming messages. This should be set if you are reading data from a file.
-L tag
Set the identifier used in syslog messages to the supplied tag This is a compatibility option for sendmail.
This is a compatibility option for sendmail.
-o option
Specifying -oi is synonymous to -i All other options are ignored.
-q [arg ]
Process saved messages in the queue. The argument is optional and ignored.
-r sender
Same as -f
Obtain recipient addresses from the message header. will parse the To: Cc: and Bcc: headers. The Bcc: header will be removed independent of whether -t is specified or not.



can be configured with three config files:

These three files are stored per default in /etc/dma  


Every file contains parameters of the form `name value' Lines containing boolean values are set to `NO' if the line is commented and to `YES' if the line is uncommented. Empty lines or lines beginning with a `#' are ignored. Parameter names and their values are case sensitive.  




SMTP authentication can be configured in auth.conf Each line has the format ``user|smarthost:password ''  


Most of the behaviour of can be configured in dma.conf

SMARTHOST (string,
If you want to send outgoing mails via a smarthost, set this variable to your smarthosts address.
PORT (numeric, default=25)
Use this port to deliver remote emails. Only useful together with the `SMARTHOST' option, because will deliver all mails to this port, regardless of whether a smarthost is set or not.
ALIASES (string, default=/etc/aliases)
Path to the local aliases file. Just stick with the default.
SPOOLDIR (string, default=/var/spool/dma)
Path to Ap s spool directory. Just stick with the default.
VIRTPATH (string, default=commented)
Path to the `virtusertable' file.
AUTHPATH (string, default=commented)
Path to the `auth.conf' file.
VIRTUAL (boolean, default=commented)
Uncomment if you want virtual user support.
SECURETRANS (boolean, default=commented)
Uncomment if you want TLS/SSL secured transfer.
STARTTLS (boolean, default=commented)
Uncomment if you want to use STARTTLS. Only useful together with `SECURETRANS'
OPPORTUNISTIC_TLS (boolean, default=commented)
Uncomment if you want to allow the STARTTLS negotiation to fail. Most useful when is used without a smarthost, delivering remote messages directly to the outside mail exchangers; in opportunistic TLS mode, the connection will be encrypted if the remote server supports STARTTLS, but an unencrypted delivery will still be made if the negotiation fails. Only useful together with `SECURETRANS' and `STARTTLS'
CERTFILE (string, default=empty)
Path to your SSL certificate file.
SECURE (boolean, default=commented)
Uncomment this entry and change it to `INSECURE' to use plain text SMTP login over an insecure connection. You have to rename this variable manually to prevent that you send your password accidentally over an insecure connection.
DEFER (boolean, default=commented)
Uncomment if you want that defers your mail. You have to flush your mail queue manually with the -q option. This option is handy if you are behind a dialup line.
DBOUNCEPROG (string, default=dbounce-simple-safecat)
Leave this entry commented if you want the default behavior of upon double bounces - just abort the delivery. Otherwise, uncomment it and specify the name or full path to a program that will process the bounced bounce message.

The program will be invoked with several command-line options:

dbounce -t dma -a bounced@email.address -i queueid -f messagefile

FULLBOUNCE (boolean, default=commented)
Uncomment if you want the bounce message to include the complete original message, not just the headers.
MAILNAME (string, default=empty)
The name to be used when introducing this host, if different from the result of hostname(1). If specified, this option overrides `MAILNAMEFILE'
MAILNAMEFILE (string, default=empty)
The name of the file to read the `MAILNAME' from.



The virtusertable file specifies a virtual user table. Each line has the format ``localuser:mail-address '' Some smarthosts do not accept mails from unresolvable email address (e.g. user@localhost) so you have to rewrite your outgoing email address to a valid address.

The utility first appeared in Dx 1.11 .
