STEP 1: Install the software: 

Log on as root or sudo and do the following:

FTP=ftp://ftp.ibiblio.org/pub/linux/distributions/e-smith/contrib/GordonRowell/RPMS/

rpm -Uvh $FTP/i386/ezmlm-idx-std-0.40-2.i386.rpm

rpm -Uvh $FTP/i386/perl-Ezmlm-0.03.1-1.i386.rpm

rpm -Uvh $FTP/i386/ezmlm-web-2.1-06.i386.rpm

rpm -Uvh $FTP/noarch/e-smith-ezmlm-web-1.1.1-05.noarch.rpm

Alternatively download the rpms to a folder and do

rpm -Uvh *.rpm

After the rpms have been installed or updated do

/sbin/e-smith/signal-event post-upgrade

/sbin/e-smith/signal-event reboot

When the server reboots and you log on to server manager, you will find a new menu item underCollaboration called Mailing Lists. This allows you to create a list with a set of modifiable default settings and set the list owner, the list administrator and also add subscribers either individually or from an existing text file and modify other configuration settings. The web interface panel allows you to select configuration options by checking tick boxes.

ADDITIONAL INFORMATION 

A couple of bugs were found during testing of earlier versions, you should update to the latest versions.

Then Modify any list and the proper permissions should be set up.

If you have installed and configured ezmlm with earlier versions of rpms in particular either or both

e-smith-ezmlm-web-1.1.1-04.noarch.rpm

and

ezmlm-web-2.1-04.i386.rpm

and receive an error message when trying to Modify the list Configuration then you need to change permissions in the ezmlm folder by doing the following:

chown ezmlm:ezmlm ~ezmlm

You should also update to the latest rpms.

If you have installed the earlier non web interface version of ezmlm on a e-smith 4.1.2 server and have upgraded the server to 5.x or 6.x and wish to upgrade to the latest ezmlm-web, you may have problems getting ezmlm to work. The new web version was deliberately made incompatible with the old non web version. You will need to do an upgrade installation (rpm -Uvh rpmname) and then manually copy the ezmlm list folder(s) from their old location to /home/e-smith/files/ezmlm/lists.

In earlier non web versions of ezmlm in e-smith 4.1.2, list folders were created in CAPITAL letters. These folders should be renamed to lower case before the ezmlm configuration can be modified using server manager web panel.

List creation: 

The switches and their meaning is summarized here. Note references for the faq and manual for ezmlm that should be referred to in full if you are going to manage these lists.

The check boxes set the following switches. An important point to remember is that leaving these switches out will not prevent a list behavior necessarily. Most switches have a default that will be used if you leave a setting out - check the faq carefully. The switches set are good safe settings but be warned they may not serve your purposes.

Here are the standard settings:

Note that these are set by checking or unchecking the appropriate tick boxes.

aBdfgHiJklMnOpQrStuWx

a =creates an archived list

B =archive access permitted (see g switch)

d =list digest will be created

f =prefix set so subject prefixed with listname

g =guard archive so only list members have access

H =subscription requires confirmation by a reply sent to subscription address

i =indexed for www archive access

J =unsubscribe requires confirmation by a reply sent to sub address

k =addresses in /deny are rejected.

l =sets up subscriber lists so remote admins can access them

M = message posting isn't moderated

n =setups up the list to allow remote administrators to edit files in /text

O =posts other than subscriber-originated are rejected

p =allow remote admin and archive retrieval

Q =don't process 'request' command

r =enable remote administration

S =subscriptions are not moderated

t =trailer; /text/trailer will be added to outgoing messages (editable by RA)

u =uses posts only

W =no address restriction

x =eXtra. Ezmlm-make will configure the list with a few extras such as stripping annoying mime parts such as excel spreadsheets, rtf text, html text etc from the messages. Messages consisting solely of this Content-type will be rejected

Common Usage/Configuration Misinterpretations: 

The "Others rejected" and "User posts only" switches should be used separately (not together) as they effectively counteract each other, unless of course you want "subscribers not moderated" behaviour for your list.

The message moderation only works for posts from subscribers when these two switches (Others rejected; User posts only) are not checked, or for non-subscriber posts, if one or both the other switches are checked.

Also you may not want to use the "User post only" switch with the "Message moderation" switch. Doing so allows subscribers and "allow" people to post without moderation.

Users are encouraged to carefully read the manual and test the behaviour of their list to ensure it does what you require.

Known bugs for fixing in next release: 

The description field for the plain english description of each list can only be set when the list is first created.

The description is not modifiable later (it was in earlier versions).

You can modify it from the command prompt by doing:

/sbin/e-smith/db accounts setprop mylist Description "Description of list"

Setting the attachment size for list messages: 

The default message attachment size is quite small (30Kb). If you wish to change the attachment size then edit the msgsize file.

Remember though, that if you have a large list of subscribers and send a message with a large attachment to the list, your server may be busy (and slow) for quite a while as the message with attachment is sent to all subscribers individually.

cd ~ezmlm/lists/listname

or

cd /home/e-smith/files/ezmlm/lists/listname

pico msgsize

change the value from

30000:2

to say

1000000:2

Ctrl o

Ctrl x

Alternatively you can include in the message a URL link to a website or ftp location where the attachment can be read or downloaded. This avoids sending large attachments to list subscribers who may not wish to receive them and also helps to reduce web traffic. The list subscriber can visit the web or ftp site if they wish to obtain the file attachment.

Modifying the default configuration: 

The default configuration of each new list is controlled by the contents of /etc/ezmlm/ezmlmrc.

The following changes have been suggested by PicsOne in this forum post

His suggested changes alter the default message attachmemt size (from 30,000 to 500,000) and change the reply to address to be the list address.

and replace the current file located in /etc/ezmlm/ folder.

A modified spanish version of ezmlmrc is here:

You can compare the files to see the differences using the diff command (assuming you copy the new file to /tmp) eg

diff /etc/ezmlm/ezmlmrc /tmp/ezmlmrc

Note that these new settings are applied when you create a new list.

If you have existing lists and wish to apply these changes then you will need to delete all your lists, then download and replace the ezmlmrc file, and then recreate the lists. Upon recreation of the list the new defaults will be applied.

If you wish to retain the data in existing lists, then you will need to backup your lists first.
If you want back up the existing users, backup the folder /home/e-smith/files/ezmlm/lists/listname/subscriber/ for each list.
Then, when you have finished recreating the list, copy your subscribers backup folders into each list.

Alternatively you can edit the applicable sections of ezmlmrc

around line 330

# max & min message size

</msgsize#x/>

30000:2

Change this to suit your requirements eg

# max & min message size

</msgsize#x/>

500000:2

around line 314

# Headeradd needs to always exist but leave out stuff for sublists

</headeradd#E^0/>

# Good for mailing list stuff (and vacation program)

Change this to suit your requirements eg

# Headeradd needs to always exist but leave out stuff for sublists

</headeradd#E^0/>

Other usage tips.

If you wish to allow list users to send html messages or any other type of attachments, go to the configuration of the list and delete all entries under "Mime types to strip from all outgoing mail". Note that you can selectively remove entries that are applicable to the type of attachment you wish to only allow.
