Configuration Settings Specific to DList:

This page details only those dmail.conf settings which apply specifically to DList.
For more settings see: DMail Config File, DSMTP settings and DPOP settings

NB: You must make DSMTP reload after changing DList lists so that it can create the aliases that it needs for the lists (check for them in the file aliases.dml in the work directory).

Sections on this page . . .

General settings for DList are contained in dmail.conf, list. Specific settings are stored in lists.dat in the dlist_path directory. You can directly edit dmail.conf and lists.dat in a text editor or use the management utility DMAdmin.

As with dmail.conf, all settings are one per line, and you can exclude a line by starting it with the # character. You do not need to reload the DList server after making changes to dmail.conf (as you do with DSMTP and DPOP), as DList automatically checks the dmail.conf and the lists.dat files before each check for list messages.

To review the list of commands able to be sent directly to lists by users, moderators and of course the DList server manager, look at the DList mail commands page. This is the page that is sent to users when they join a list.

Dmail.conf settings used by DList:

List Specific Settings in lists.dat:

Note: Access settings can generally take one of the following settings,

  • member - refers to list members and in general the list moderator as well
  • anyone - no restriction
  • moderator - only the list moderator can do it
  • *domain - the person trying to do it must have the email address ending in 'domain'

Setting Default Example Description
access_join anyone *netwinsite.com Controls who can join the mailing list
access_leave anyone in version 2.5d (2.4k) and above:
members: (can unsubscribe themselves, moderator can unsubscribe anyone)
moderator: (only moderator can unsubscribe - members cannot unsubscribe themselves)
Controls who can unsubscribe from the mailing list, by default anyone can unsubscribe anyone else.
access_post members moderator Controls who can post messages to the mailing list
access_who members anyone Controls who can retrieve the list of current members
archive false true If set, DList will record all incoming messages in an 'archive' sub directory, off the list's directory.
footer (version 2.4h and above) (none) footer
c:\dmail\dlist\listname\footer.txt
The full path to a file that you want added onto the end of all messages as a footer.
from_list ???? from_list ???? ?????
join_cookie false true If set, when users join the list they will be asked to respond with a specific cookie (number) to prove that they are real humans. This setting prevents people from subscribing other people, or worse, other lists to an existing list.
list (none) dnews-discussion The name of the list. This cannot contain spaces, and must be the first setting for each new list in lists.dat
max_size 40K 100K Limits the maximum size of an item that can go through the mailing list. You should follow the number value with a units multiplier, e.g. k, Mb etc.
max_per_user
(2.4g and above)
200
(changed from 50 in vers. 2.5d)
1000 Sets the max number of messages allowed to be posted to all lists on the server per user per hour. Note: the count is per user for posts to ALL lists, whereas the setting is per list. So the count is global but whether it applies to a list is list specific (the default is 200).
moderator (none) fred@netwinsite.com A list of one or more moderator email addresses. A moderator often has extra access rights, like the ability to subscribe other people etc. Separate multiple entries with spaces or tabs (or commas in version 2.5d and above)
reply_to_user false true If set, the reply-to header in each message will be pointed to the original poster, rather than the mailing list, this is recommended for large mailing lists.
status_interval 7 1 Period in days between automatic status reports being sent to the moderator.
skip_mailer_check false TRUE If TRUE, DList will not ignore messages from users called, MAILER-DAEMON (all in capitals). These are normally bounced messages and so would not normally be wanted as posts to the list.
skip_postmaster_check FALSE TRUE If TRUE, DList will not ignore messages from users called, POSTMASTER (all in capitals). These are normally bounced messages and so would not normally be wanted as posts to the list.
subject_prefix (none) Juggle: This string will be added to the front of every subject line of messages from this list. This makes it easy for people to sort list messages out from other messages.
title (none) N.Z. Juggling A title for the list, shown in headers and lists output.
Settings still to document:
path, access_put,
access_get, access_overwrite,
bounce_remove,
domain,
invisible,
password, from,
list_global

Creating a Mailing List

To create a mailing list on the list server DList, you need to add a new list setting in the lists.dat file, e.g.
list listname
where listname is the name of the list. You can edit the lists.dat file with a text editor (e.g. notepad or vi). Alternatively, the windows administration tool
DMAdmin will edit the file for you if you use the "Mailing Lists" button.

If you are doing it manually, add any other settings that you require for your list below the list setting , e.g.
title title of my list

Then RESTART the DSMTP server with DMAdmin. You must restart DSMTP after changing DList lists so that it can create the aliases that it needs for the lists.

In order to try out the list, you should add a user to the list and then post a message to the list. For information on this, see
Adding Users to a List
DList Email Commands


Welcome Messages

DList comes with an example welcome message. It is stored in a file called join.tpl in a template format.

You can edit this template to the look that you require, and you can copy it to each list's directory (off the main DList directory) so that individual lists can have their own welcome message.

The template can use the following template variables, which will be replaced by DList with the appropriate information. A template variable is parenthesized with double percent signs, e.g. %%variable%% so that DList can recognize it as a variable.

%%list-name%% BigListThe name of the list.
%%list%% biglist@domain.comThe address that list members send messages to post on the list.
%%list-request%%biglist-request@domain.comThe address that people send list request messages to, e.g. in order to subscribe.
%%h_user%%bobThe username of the 'person' who has joined the list.


Adding users to a list

Usually, users would add themselves to a list by sending a message to the list request address, e.g. listname-request@domain with the word subscribe in the message body.

DList will then add them to the users.lst file for that list. Users.lst for each list is stored in that list's directory (named after the list), off the DList directory (probably \dmail\dlist\listname\users.lst or /usr/local/dmail/dlist/listname/users.lst )

To add a number of users you have two options:

  1. Add yourself as a moderator for the list and send the listname-request address a message with multiple subscribe lines in the body.

    So, as a moderator, you send the following email:

    To: listname-request@domain
    From: your_moderator_address

    subscribe bob@domain1.com
    subscribe judy@domain1.com
    subscribe george@domain99.com

    to join up the email addresses,
    bob@domain1.com
    judy@domain1.com
    george@domain99.com

  2. Directly edit the users.lst text file for the list and add the email addresses, one per line.

    So, to add the same three users, you might edit the users.lst file to look like this:

    u:tam@1.2.3.4 f:Tam Willacy p:0 t:0
    bob@domain1.com
    judy@domain1.com
    george@domain99.com

    where the first line is an existing user on the list.

    Don't worry about the format of lines for existing users. The next time that DList has to write anything to the users.lst file it will add the email addresses that you have pasted/typed in correctly.


Moderated lists

This is still being written :-)

There are two ways of posting into a moderated list, depending on whether the access_post setting is set to Password or Moderator:

  1. Password: DList accepts the message from the user and sends it to the moderator, who, if they want to approve it, then submits it to the list with the first line of message body being
    approve Password
    e.g.
    approve xxxx

    For this to work, the access_post setting for the list in lists.dat must be set to 'Password' and the list password setting must match the password given in the approve line, e.g.
    access_post Password
    password xxxx

  2. Moderator: The return address of the incoming message matches that of the moderator setting and the access_post setting is set to Moderator in the lists.dat file, e.g.
    access_post Moderator
    moderator moderator@domain

    where moderator@domain is the address that must match.

Notes:

  • There must always be a moderator for a list set to password post access because password is a more secure moderated list.


Archives and Files

This is still being written :-)

DList lists can be set to save an archive of all messages by setting the list specific setting in lists.dat,
archive true

If this is set, DList will create the archive messages in a subdirectory called, 'archive' below the list's directory, e.g.
c:\dmail\dlist\listname\archive\1.msg
c:\dmail\dlist\listname\archive\2.msg

etc.

Then if the user sends an email to the listname-request address with the command 'dir' in the message body, then DList will send back a message telling the user how many archived messages there are.

If the user wants one of the messages, they can send the 'get' command to fetch the archived message.

If you want to provide other files to the list members, you create your own directory off the list's directory called 'files' and put the files that you want to provide there, e.g.
c:\dmail\dlist\listname\files\picture.jpg

Then when the user does a 'dir' command, they will also be shown a list of other files available.

For details on the list commands see, DList Email Commands
