La Plaza Mailing Lists

A mailing list (or listserve) is a group of email addresses that can all be reached by sending a single message to one address:  the list address.
Messages sent to the list are distributed to each of the list subscribers.  By sending messages to the list, subscribers can have ongoing
discussions with each other and need only keep track of one address.

Mailing lists are good for many things including:

La Plaza offers mailing list owners limited control over the creation and maintenance of their list(s).  La Plaza uses Mailman software.
To see the mailing lists hosted on our server please go to La Plaza Mailing Lists.  If you are interested in starting up a list and having La Plaza host it please Contact Nancy Montano or go to the New Mailing List Request page.

What is MailMan?

MailMan is software to help manage email discussion lists, much like Majordomo and Smartmail. Unlike most similar products, Mailman
provides a web based interface that gives each mailing list a web page, and allows users to subscribe, unsubscribe, etc. over the web. Even the
list manager can administer his or her list entirely from the web. Mailman also integrates most things people want to do with mailing lists,
including archiving, mail-to-news gateways, and so on.

La Plaza is the administrator of Mailman for all mailing lists that exist on our server.

Types of Mailing Lists on La Plaza
La Plaza supports the following mailing list subscription policy.

Allows anyone to subscribe themselves to the list without approval from the listowner.  Attempts to subscribe addresses, other than the sender, require approval. The mailing list is accessible to anyone on the Internet as well as La Plaza users.

This mailing list is only accessible to people approved by the listowner. Requires list owner approval for every subscription request.


Open unmoderated lists tend to place a significant load on the Mail servers in which they run.  The freedom to send any type of message to
the whole list, sometimes make them prone to losing focus, quality of intercourse and even abuse by some members.  Then the good
members start to unsubscribe in order to reduce the size of their mailboxes, leaving only the bad apples in the tree.

La Plaza’s MailMan program is set with certain limits.
The first limit is the header size. The limit is 1024 Kb. This limit is imposed so that our Mailing Lists are not abused, or used for "spamming".

The second limit is the message size. This limit is 40,000 Kb. This limit is imposed so that huge files are not passed back and forth on our
mailing lists, causing unnecessary strains on our servers.

If either of these limits is reached, the message will be bounced to the list owner and a message will be sent to the sender informing them
that their message has been held. If you must send a message larger than 40,000 Kb to a mailing list, break it up into sections.  Neither of
these limits is open to change.

How to Join a La Plaza Mailing List?
You can subscribe or unsubscribe to any La Plaza mailing list by using our easy web interface available at  Select the list you want to join.  This will take you to the List Information Page divided into
sections.  The first section directs you to the list's archives if they are available.  (See the Mailing List Archive section for more
detailed information.)  The second section tells you how to send a note to the list. Note that the conventional list configuration
prevents postings from the list from people who are not subscribed:  so if you try to send a note to the list before you join, the
message will probably be rejected and returned to you.
The third section provides you with an simple form that you must fill out to join the list.

Subscribing to a list is simple and includes safeguards to prevent abuse of the list.  In the subscription section type you email
address and then select a password.  The password will be used later when you want top log in and change your personal settings.

When you fill out the form you have the option of receiving mail from the list you join in a daily digest.  This is convenient if you are a

member of a number of lists or if the list you join has a lot of traffic.  You can always change this option at a later time as detailed in
the "options" section below.

After you supply your e-mail address and password, press the subscribe button to add yourself to the list.  Your addition is not

immediate.  After you submit the form, MailMan will send you an e-mail message to the address that you used to subscribe.  The
message that you receive will ask you to confirm your request.  This is to prevent someone from adding you to mailing lists that you
do not want to join.  When you receive the confirmation request just follow the instructions - the simplest thing being just to hit the
"reply" button in your mail program.  If you send the message back without altering the subject line (the Re: added by your mail
program is OK) then your confirmation will be accepted.

After successfully confirming your subscription, MailMan will send you a welcome message.  The note will include the following

important information:

The URL that takes you directly to the list's information page

The URL that takes your directly to your own personal settings page
Your password.

Keep this message in a safe place.  You will need the information if you ever want to modify your personal settings or remove

(unsubscribe) yourself from the list.
Managing Your Subscription(s) to La Plaza hosted mailing lists
Once you are in the list information page you can manage your own personal settings.  It is important to keep in mind that you have a separate password for each of the lists that you are subscribed to, even though they may be on the same mail server.  For your convenience, you may want to visit each list and set your password(s) to something common.  Remember changing your password on one list does not change it on other lists.  If you ever forget your password, you can request that it be sent to you from the list
subscription options page.

The bottom of the list information page allows you to view who is subscribed to the list.

To unsubscribe or change your list options you must first go to the list information page.  The best way to access this page is by going to the URL delivered in your welcome message.

If you do not have it handy, then you can go directly to the list information page if you know the name of the list.  At the bottom of this page  is a blank that allows you to enter your email address and click the edits option button.

You will then be taken to the List Configuration Page. When you reach this page, the screen is divided into three sections.  You can unsubscribe, access other lists you are one, request you password be emailed to you, change your password and change your subscription options.

Unsubscribing from a list
To unsubscribe or remove yourself from the list all you need to do is put your password in the blank and click the unsubscribe button.  This password is required to prevent other people from removing you from the list without your authorization.

Password options

This section provides you with two options. First, it allows you to look up your password if you have forgotten it.  For security purposes it will email your password to you, thereby preventing unauthorized access to your password.

The second section allows you to change your password.  You need to type in your old password once and then the new password twice.  It is a good security habit to change all of your passwords once a month; it is also a good idea to change your password from the computer generated random password.

Accessing other lists

It is likely that you may be subscribed to several lists on the La Plaza server.  MailMan allows you to jump from one list configuration screen to the other through the use of the "other subscriptions" feature.  This is useful, for example, if you are going on vacation and need to change to the no mail option on several lists while away.

General subscription options

At the bottom of the configuration screen are the general subscription options for the list as they are set for your account.  When you first load this page the options reflect your current settings.  These are default settings that have been set up by the list administrator.  You may make changes to these settings and then put them into effect by typing in you password at the bottom of the screen and then clicking on the "submit my changes" button.

Here is a summery of the settings and what they mean

Disable Mail Delivery
You need to look at this setting carefully if you are thinking about changing it. The settings may mean the reverse of what you think they do:
Off: mail delivery is not disabled. "Off ' means that you will receive mail. 
On: mail delivery is disabled. "On" means that you will not receive mail. 
Set Digest Mode
Off. messages sent to the list will be delivered to your one at a time. 
On: mail sent to the list will be collects by the server, batched together, and then mailed to you daily as a single, large message.
Get MIME or 

Plain Text Digests

MIME is a way of sending mail that allows for document formatting and the easy shipping of attachments. Most modem mail readers can handle MIME mail; older, text-based mail readers may have problems.
MIME: digests will be sent in MIME-compliant format. 
Plain Text: use this setting if your mail reader has problems with MIME digests. 
Receive posts you send to the list? 
Yes: messages that you send to the list will be sent to your account.
No: you will not receive a copy of messages that you send to the list. Some people find copies of their own messages annoying, this option will prevent then from having to read their own words.
Receive acknowledgment mail when you send mail to the list?
No: when you send mail to the list, you will have to assume that your message has been successfully received by the list manager and is on its way.
Yes: when you send a note to the list the list manager will send acknowledgment of its receipt. This is particularly helpful in two instances: when you are subscribed to the digested version and will not see your own posting until the following day; and when the list is moderated and the moderator may not review/forward your note to the list for some time.
Conceal yourself from subscriber list?
No: people who have access to the "view list members" option will be able to see that you are a member of the list.
Yes: people who have access to the "view list members" option will not be able to see you listed even though you are a member of the list and receive messages.

As mentioned above, after making changes to any of these settings you should then type your password into the space provided at the bottom of the screen and click the "submit my changes" button.  After submitting your changes the page will be reloaded and the settings should reflect any modifications that you made.

Mail list archives

Most list managers will choose to activate MailMan's powerful archival features to make list traffic available to members. MailMan makes it archives available through each list's information page. Keep in mind that the list manager may have chosen not to archive a particular list to which you belong. Also keep in mind that it is a general practice to make the list archive available only to individuals who are subscribed to the group.

If the archive is "open" then you will be able to go straight in from the information page. If the archive is for subscribers only then you will be prompted for your e-mail address (make sure to use the address that the list knows you as) and your list password. Once in, you will be shown a historical listing of list traffic similar to the one shown at right.

The default setting for the archive is to divide messages by month. Do not be surprised, however, if you see some other division of the archive contents: the list manager decides how things will be divided up. There are different viewing options for each month:

The final option allows you to download a Gzip'd version of the archive text. Gzip is a compression utility whose files end  in gz. Most "zip" utilities are able to open Gzip'd files. When you download and unzip this file you will have the entire contents of the archive's period.

After you have chosen how you wish to view  the archive you will see the headers of the notes displayed according to your specified

criterion.  To read an individual note just click on the subject line. When the note appears there will be additional navigational
information allowing you to see the previous or next messages (as you had them sorted), or to request the listing of all of the notes again sorted by a different criterion.
