dma (0.0.2010.06.17-3) unstable; urgency=low
The default delivery mode has been changed to immediate, as it is in
the upstream version of dma; the DEFER keyword is now disabled by default
in dma.conf.
-- Peter Pentchev <roam@ringlet.net> Tue, 27 Jul 2010 13:26:48 +0300
dma (0.0.2010.06.17-1) unstable; urgency=low
The dma spool directory format has changed. The Debian package of dma now
recommends a separate package containing the dma-migrate utility; if it is
present, it will be invoked at each periodic dma queue flush and attempt to
convert the existing old-style queued messages to the new format. In most
cases, this should not incur any performance penalties in normal operation,
since dma-migrate will scan the spool directory and ignore any new messages
(they should already be in the new format); however, if it appears that
the periodic queue flush runs take longer than usual to start up, you may
remove the dma-migrate package once you have ascertained that your queue
directory (/var/spool/dma) only contains files with names beginning with
the letters M or Q.
This version of dma knows how to perform MX lookups, so remote delivery is
now possible directly, not through a smarthost. However, a smarthost setup
might still be preferred on many systems for various reasons - e.g. dynamic
address assignment, a central outgoing mailserver, a roaming laptop, etc.

dma for Debian
--------------
Smarthost operation by default - needs to be configured!
After first installing dma, you need to configure it for proper operation -
whether it should deliver all outgoing e-mail messages through a single
smarthost or attempt to contact the remote mail servers directly. This should
be configured through the debconf questions, but you may change the setting
using the SMARTHOST directive in the /etc/dma/dma.conf file.

- fixes some queue locking problems; Closes: #582593
- adapt the rules file to use the GNU Makefile instead of the BSD one
- drop pmake from Build-Depends

- enhance the 11-double-bounce patch a bit:
- use dma's own delqueue() function instead of a naive unlink() so
all the queue files are cleaned up
- document the Debian default for DBOUNCEPROG in the manual page
- resurrect the 13-hardening patch, correcting a couple of
unchecked asprintf(3) and vasprintf(3) invocations
- the functionality of the 20-parse-recipient patch was implemented
upstream in a different way, so replace it with a small bugfix
- remove the 22-openfiles patch, overtaken by upstream changes
- in the 24-random-message-id patch, change the GNU Makefile, too
- add the 27-int-size patch to cast a variable to the correct type
- add the 28-valid-recipient patch to fix parsing recipients out of
the message body
- add the 29-double-free patch to fix a double-free error
- add the 30-ldflags patch to honor LDFLAGS if specified
- refresh the 09-typos, 17-mailname, 23-dirent-d_type, and
25-unsupported-starttls patches
- teach the dbounce-simple-safecat handler about the M*/Q* spool
files scheme
* Bump Standards-Version to 3.9.0 with no changes.
* Update the copyright file:
- bring it up to the latest revision of the DEP 5
- update the upstream copyright notices
- bump the year on my copyright notice
* Remove the diffsrc rules target which was intended for my own
internal use, but has outlived its time.
* Use dpkg-buildflags from dpkg-dev >= 1.15.7~ to get the default
values for CFLAGS, CPPFLAGS, and LDFLAGS; no longer rely on
dpkg-buildpackage to set them by default.
* Add the dma-migrate utility (in a separate binary package) to convert
spool files to the new queue format (M* and Q* files for each message)
* Add a dma-migrate invocation to dma.cron.d
* Shorten the Vcs-Browser URL.
* Add the 31-sigalrm-backoff patch to force a delivery attempt on SIGALRM.
* Properly substitute the debconf-supplied values for DBOUNCEPROG and
SMARTHOST into dma.conf even if they are empty without generating
an invalid dma.conf file.
* Remove the smarthost default; dma does MX lookups now, so it doesn't
really *need* one anymore.
* Reword the debconf relayhost question - dma does not really need
a smarthost anymore.
* Update the debconf translations:
- Bulgarian
- Portuguese by Américo Monteiro
- German by Helge Kreutzmann; Closes: #586531
- Russian by Yuri Kozlov; Closes: #586579
- Czech by Michal Simunek; Closes: #586791
- Swedish by Martin Bagge; Closes: #586825
- Spanish by Francisco Javier Cuadrado; Closes: #587088
* Update the smarthost configuration information in README.Debian.
* Add the 32-comment-uncomment patch to correct the manual page wording.
* Add the 33-opportunistic-tls patch to allow remote connections to proceed
even if the STARTTLS negotiation fails.
* Fix the 25-unsupported-starttls patch to actually error out if the SSL
negotiation fails.
* Forward all the non-Debian-specific patches upstream to Simon Schubert.
* Add the 34-manpage-defaults patch to properly document what dma will use
as default values if not specified in the config file instead of what
the default config file specifies. Closes: #544748
* Add the 35-delivery-retry patch to try local deliveries a bit more often
and to randomize the delivery timeout to avoid locking issues.

dma (0.0.2009.07.17-3) unstable; urgency=low
* Really install the files in /etc/dma/ as root/mail/640 and
change the ownership of the existing files in the postinst script
when upgrading from older versions. Closes: #544664
* Install the /usr/bin/mailq and /usr/bin/newaliases symlinks.
Closes: #558421
* Switch to the 3.0 (quilt) source format.
* Update the debconf translations:
- add German. Closes: #552754
- add Japanese. Closes: #554515
- remove a double space and unfuzzy the translations. Closes: #552586
* Fix a crash when the SMTP server does not support STARTTLS.
Closes: #547594
* Always use the user-supplied value from the debconf query for
the smarthost and the double-bounce program. This may result in
debconf overriding a manually-edited config file, so add a note to
dma.conf stating that these values are handled via debconf.
Closes: #544663
* Fix a misspelling of dma/dbounceprog as dma/defer in the debconf
configuration script. Oops.

dma (0.0.2009.07.17-2) unstable; urgency=low
* Allow the spool directory to live on a filesystem that does not
set the d_type member of the dirent structure, like XFS.
Closes: #544357
* Randomize the Message-Id a bit more. Closes: #544475
* Bump Standards-Version to 3.8.3 with no changes.
* Only enable the build hardening wrapper if the "hardening" build
option is specified.
* Switch the copyright file header from the Wiki to DEP 5.
* Remove the manual page ".Dx" patch - the groff version in Squeeze
knows about the .Dx mdoc macro. Add a lintian override for
the "Unknown DragonFly version" error.
* Convert the patch file headers to the DEP 3 format.

Description: lightweight mail transport agent
The DragonFly Mail Agent is a small Mail Transport Agent (MTA),
designed for home and office use. It accepts mails from local Mail
User Agents (MUA) and delivers them either to local mailboxes or
remote SMTP servers. Remote delivery includes support for features
such as TLS/SSL and SMTP authentication.
.
dma is not intended as a replacement for full-featured MTAs like
Sendmail, Postfix, or Exim. Consequently, dma does not listen on
port 25 for incoming connections.
Package: dma-migrate
Architecture: any
Depends: ${shlibs:Depends}, ${misc:Depends}
Enhances: dma
Description: migration utility for the DragonFly Mail Agent's spool files
The dma-migrate utility examines the DragonFly Mail Agent's mail queue
and performs any conversions from old message file formats to the most
recent one as needed.

.Os
.Sh NAME
.Nm dma-migrate
.Nd convert the DragonFly Mail Agent's queue files
.Sh SYNOPSIS
.Nm
.Op Fl v
.Op Fl d Ar spooldir
.Nm
.Op Fl h | Fl V
.Sh DESCRIPTION
The
.Nm
utility is used to convert the mail queue files in the
.Xr dma 8
spool directory to the latest spool directory format supported by
the installed version of
.Xr dma 8 .
Currently it only handles the conversion from a single file containing
both message and delivery metadata to the M/Q format.
.Pp
The following command-line options are available:
.Bl -tag -width indent
.It Fl d
Specify the location of the
.Xr dma 8
spool directory, default
.Pa /var/spool/dma .
.It Fl h
Display usage information and exit.
.It Fl V
Display program version information and exit.
.It Fl v
Verbose output - display diagnostic messages.
.El
.Sh ENVIRONMENT
The operation of the
.Nm
utility is currently not influenced by environment variables.
.Sh FILES
The
.Nm
utility looks for the
.Xr dma 8
mail queue files in the
.Pa /var/spool/dma
directory, unless another location is specified by the
.Fl d
command-line option.
.Sh EXIT STATUS
The
.Nm
utility will scan the whole spool directory and attempt to convert all
suitable files there.
If there are no files to be converted, or if all the conversions are
successful, it will complete with an exit code of zero.
If any conversion errors are encountered, a message will be displayed
to the standard error stream and
.Nm
will exit with an exit code of 1 after attempting to convert the rest of
the suitable files in the spool directory.
.Sh SEE ALSO
.Xr dma 8
.Sh STANDARDS
No standards documentation was harmed in the process of creating
.Nm .
.Sh BUGS
Please report any bugs in
.Nm
to the author.
