Section 3 Working with Mailing Lists
3.1 Finding a Mailing List using CataList
CataList, the catalog of LISTSERV lists, can be accessed at http://www.lsoft.com/catalist.html or, if you are logged into LISTSERV, by clicking on the CataList icon at the bottom of each screen. You can also access the CataList from the Server Archive Index (see Section 4.1 The Server Archive Index for more information.)
Figure 3-1 CataList
CataList lets you browse any of the 56,128 public LISTSERV lists on the Internet, search for mailing lists of interest, and get information about LISTSERV host sites. While many of these public lists do screen new subscriptions, this is usually done to make sure that newcomers understand what the list is about and, perhaps more importantly, what it is not about. As long as you respect the list charter (set of rules for members), you can reasonably expect to be welcomed on any of the lists that you find in this database.
3.1.1 Searching for a List
You can search this database in a variety of ways to find a list of interest. You can browse through a set of lists by country, by host country, with 1,000 subscribers or more, or with 10,000 subscribers or more by clicking on the link that corresponds with each category. Or, you can perform a search to find a list with specific criteria. To start your search, simply click on the Search link under List Information or Site Information.
Figure 3-2 Searching for a List
Read the on screen instructions for search criteria, including the use of multiple search strings. Input your search criteria in the edit box. Check the appropriate checkboxes to narrow or widen your search and then click the [Start the search!] button. The default home page will appear for the list.
If you have any questions about a specific list, direct them to the list owner. The list owner is always reachable by email at an address formatted like this:
listname-request@domainaddrress
There are usually directions on how to subscribe to the list as well as a description of what the list is about on the home page.
3.2 Communicating with LISTSERV
LISTSERV was created before the World Wide Web was in general use. At that time, the primary way for most people to communicate with the LISTSERV program was by email. This method is still widely used today. The most recent versions of LISTSERV include a Web Interface to make communication easier and more intuitive. The Web Interface is richly populated with on-screen information, tutorials, and wizards to help you use the program quickly and effectively.
When you want to perform actions using LISTSERV, such as subscribing to a list, the action is based on a command LISTSERV receives by email or using the Web Interface. Some commands are only available to LISTSERV maintainers and list owners, while other commands are available to subscribers and non-subscribers as well.
3.2.1 Using the Web Interface
As a subscriber, you can use the Web Interface to issue commands directly to LISTSERV. You can also use the Web Interface to post messages to the list. To use the Web Interface you need a Web browser. L-Soft recommends Internet Explorer™ version 5.0 or greater or Netscape® 6.0 or greater for the best compatibility. You will also need the URL to the installation of LISTSERV where your list(s) is located, called the LISTSERV Homepage.
Click on the Subscriber's Corner option to begin using the Web Interface to join, leave, or change subscription settings for lists on that server. For more information, see Section 3.3 The Subscriber’s Corner.
3.2.2 Using Email
There are two main -mail addresses that are used to work with LISTSERV lists. One is to communicate with the LISTSERV program – the command address, and one is used to post mail to the list – the list address. Any time you want to change your subscription settings, communication takes place with the LISTSERV program using the command address. Whenever you post a message to the list, it is sent to the list address. It is important to understand the difference between the two addresses.
Caution: If you send commands to the list address, every member of the list will receive your command, and LISTSERV will not take any action. If you send a normal posting to the command address, LISTSERV will send you back an error message because it will not be able to interpret the message, and none of the subscribers will receive your post.
The command address will usually start with “LISTSERV@” and will be followed by the server name where the LISTSERV program has been installed, such as LISTSERV@papaya.ease.lsoft.com. Messages sent to the command address should contain only commands to LISTSERV, one command per line. Lines containing non-commands will result in an error message being returned. For a list of LISTSERV commands, their descriptions, and how to issue them, see Appendix A: Command Reference Card.
Email Command: You can also get a listing of commands by sending an email message to your LISTSERV server with INFO REFCARD typed in the body of the message. Do not include a subject in the subject line and do not include anything else in the body of the email message such as a signature file.
3.3 The Subscriber’s Corner
The Subscriber’s Corner screen lets you see the lists that you’re subscribed to or all public lists on the server. The list table displays the selected subscription settings for each list. The following actions can be performed from this screen:
Subscribing to One or More Lists
Unsubscribing from One or More Lists
Changing Subscription Settings
Sending Mail to a List
The Search for List field lets you narrow the selection of lists to those containing a specific text in the listname. Enter the text to search by (e.g. sales) and click [Search].
If Show Subscribed Lists Only is selected (the default) from the Show All Lists drop-down menu, then only lists that you are subscribed to are displayed. If Show All Lists is selected, then all lists on the server that you are subscribed to and any public lists on the server that you are not subscribed to are displayed. The selection of lists is also subject to the setting of the Narrow Selection field (if in Expert Mode). Lists that you are subscribed to will be highlighted with a clickable link.
The Lists per Page field controls how many lists will be displayed on a single page. The default is 50. If you want to show 10 lists per page, then enter "10" and click [Submit].
3.3.1 Subscribing to One or More Lists
To subscribe to one or more lists, click the Show All Lists drop-down menu and select Show All Lists. Check the boxes next to the lists that you want to subscribe to, and then click the Invert drop-down menu and select Subscribe. Check the Send email notification of changes option to have a notification email sent with information about the changes. Finally, click the [Submit] button.
Note: If you select the Invert checkbox, then the changes selected will be applied to the lists that are NOT checked.
Tip: To subscribe to one list at a time, you can simply click the Settings option next to the list name (this option is located on both tabs). This opens the Join or Leave List screen. For more information on this screen, see the online help or see Section 4.5 Joining, Leaving, or Updating a List from the Archives.
3.3.2 Unsubscribing from One or More Lists
To unsubscribe to one or more lists, click the Show All Lists drop-down menu and select Show Subscribed Lists Only. Check the boxes next to the lists that you want to unsubscribe from, and then click the Invert drop-down menu and select UnSubscribe. Check the Send email notification of changes option to have a notification email sent with information about the deletions. Finally, click the [Submit] button.
Note: If you select the Invert checkbox, then the changes selected will be applied to the lists that are NOT checked.
Tip: To unsubscribe from one list at a time, you can simply click the Settings option next to the list name (this option is located on both tabs). This opens the Join or Leave List screen. For more information on this screen, see the online help or see Section 4.5 Joining, Leaving, or Updating a List from the Archives.
3.3.3 Changing Subscription Settings
The My Settings tab on the Subscriber’s Corner screen lets you select which columns will be displayed in the list table. In addition, you’ll be able to change specific list settings for one or all of your lists.
To select the columns to view in the list table, check one or more boxes in the Report Columns section, and then click the [Submit] button to display the relevant subscription options. To check all boxes, click on Check All. To clear all of the selections click on Uncheck All.
Note: Some columns are only available while using LISTSERV in Expert Mode. For more information, see Section 3.6 Setting Your Personal Preferences.
Figure 3-3 Selecting the Columns for the My Settings Tab
The following columns can be displayed:
Mail Style – Check this box to report on whether subscriptions are set to receive individual postings (Regular), or Digest or Index versions of the list.
Regular – You receive each individual posting as they are processed by LISTSERV. With this subscription type you may receive mail throughout the day. Each posting will arrive as an individual message in your mailbox. For small lists, or less active lists, this type of subscription works well. Large busy lists can send many messages throughout the day and it may become distracting or fill up you mailbox.
Digest – You receive a large message containing many individual posts bundled together into one, at regular intervals, usually once a day. Some very active lists will produce several digests a day. Receiving the digested version of a large active list will limit the number of messages you get during the day.
Index – You receive a short index of messages at regular intervals, usually once a day or once a week. The index displays the date, author's name, e-mail address, the subject of the message, and the number of lines in the message. You can download the full text of any messages that are of interest without having to receive every message. If you have limited inbox storage, this form of subscription will cut down on the amount of space messages take. You do, however, have to be online to retrieve any messages you wish to read.
Mail Status – Check this box to report on whether subscriptions are set to receive postings (Mail) or not (No Mail) from the list.
Restrictions – Check this box to report on what, if any, posting restrictions are in effect for the subscriptions. The following restrictions are available:
Post – Normal posting privileges according to the list's configuration.
No Post – The subscriber is not allowed to post to the list.
Editor – Posts bypass moderation on a list that is configured for moderation as policy.
Review – All posts are sent to a moderator for approval before being permitted on the list.
No Review – Posts are not sent to a moderator for approval before being permitted on the list.
Subscription Date – Check this box to report the date on which each subscription was registered. If this is blank, the subscription was registered before the LISTSERV server was upgraded to version 1.8c (which was released in 1997).
Header Style – Check this box to report on the "header style" subscriptions that are set to receive for list postings. Possible header styles are:
Full – Normal headers for list postings. List name is always the To: header.
Subject – Same as Full, but a subject-tag identifying the list is added to the subject header of all postings.
Short – Only the bare minimum headers (To:, From:, Date:, and Subject:) are included.
Warning: This setting will break MIME messages; therefore, it should only be used on lists that allow plain text or for subscribers using mail clients that cannot handle MIME mail.
Dual – Same as Full, but the main headers are repeated inside the message text as well. This is to accommodate some old mail software that did not process Internet mail properly, and is mostly obsolete.
IETF – Headers are exactly the same as those sent by the original sender, with the possible exception of adding a "Sender:" line (depending on the list configuration). This may break filters on some mail clients that rely on all list mail having certain mail headers look the same on all list postings.
Full (822) – "Full" mail headers (like the default) except that the To: header contains the recipient's email address instead of the list address.
Short (822) – Only the bare minimum headers (To:, From:, Date:, and Subject:) are included. In addition, the To: header contains the recipient's email address instead of the list address.
Warning: This setting will break MIME messages; therefore, it should only be used on lists that allow plain text or for subscribers using mail clients that cannot handle MIME mail.
Conceal – Check this box to report on whether or not subscriptions are listed in a "Review" of the list of subscribers. This setting is only of interest for lists where the list of subscribers is viewable by other list members or the general public.
This setting is mostly superfluous on lists that are set such that only the list owners can review the list of subscribers because list owners can always see the subscriber addresses regardless of the Conceal setting. However, list owners may set the list such that Conceal is the default option for all subscribers to indicate that subscriptions are allowed without requiring the first and last names of the subscriber.
Topics – Check this box to report on which topics subscriptions are set to receive on lists configured with topics.
HTML – Check this box to report on whether or not subscriptions are set to receive Digest or Index versions of the list as HTML. This setting is irrelevant for subscriptions set to receive individual postings ("Regular" mail style).
MIME – Check this box to report on whether or not subscriptions are set to receive Digest versions of the list as MIME. This setting is irrelevant for subscriptions set to receive individual postings ("Regular" mail style). This setting is required for HTML Digests; therefore, it should be viewed in conjunction with the HTML setting.
Ack – Check this box to report on whether or not subscriptions are set to receive an "acknowledgement" message when they post to the list. For example:
Your message dated Thu, 2 May 2002 16:08:28 -0400 with subject "My message" has been successfully distributed to the MYLIST list (123 recipients).
See also the Repro setting.
Repro – Check this box to report on whether or not subscriptions are set to receive a copy of their own postings. Some subscribers want to receive a copy of their own postings, others are satisfied with just a short acknowledgement (see the Ack setting) and the copy that their mail client keeps, while others want both or neither.
Renew – Check this box to report on whether or not subscriptions are set to receive renewal notices on lists that are configured to request subscription renewals. This setting may only be changed by a list owner.
To change specific list settings for one or all of your lists, check the box that corresponds with that setting in the Report Columns section and click [Submit]. The My Settings tab refreshes, displaying the settings you selected. Next, click the box next the name of the list you want to change, click the drop-down arrow at the bottom of the column for the setting you want to change, and then click [Submit].
For example, if you wanted to change the Mail Style setting on all of your lists, simply click that checkboxes for those list, click the drop-down arrow at the bottom of the Mail Style column, select the setting you want (e.g. Digest), and then click [Submit].

3.4 Verification and Confirmation Messages
Most lists have some type of security engaged to prevent spoofing and spamming. Spoofing occurs when someone signs you up for a list without your knowledge and permission. Spamming is the act of cross-posting the same message to as many newsgroups and/or mailing lists as possible, whether or not the message is relevant to the stated topic of the newsgroups or mailing lists that are being targeted. It also refers to unwanted e-mail solicitations sent to an individual whose e-mail address has fallen into the wrong hands. To read more about LISTSERV and spamming, see the SPAM-L list, available on LISTSERV@peach.ease.lsoft.com.
When you elect to join a list, you will usually be sent a confirmation message by email. Directions will be included in the message so that you can confirm that you did actually agree to be subscribed to the list. Follow the directions to confirm your subscription.
3.5 Sending Mail to a List
After you have subscribed to a list you will eventually want to participate in the discussion, assuming that you have joined a list where subscribers have permission to post (on some lists you are not allowed to post mail back to the other subscribers). For more information on the different types of mailing lists, see Section 1.4 Types of Mailing Lists.
3.5.1 Using the Web Interface to Post a Message
There are two ways to post a message to a list using the Web Interface:
The archives for a list give you the option to post a message from the List Archive screen, the Archive Index, and the Archive Browsing screen. For more information on these screens, see Section 4.2 Viewing List Archives, Section 4.3 The Archive Index, and Section 4.4 Viewing an Archived Message. To access the list archives, click Email Lists on the Toolbar. To compose and send a message to the list from the archives, click the Post New Message option on any of the screens previously mentioned. The Send Message screen opens (shown in Figure 3-5), which is where you compose your plain text, HTML, or multi-part messages. See below for information on the Send Message screen.
The Subscriber’s Corner screen lets you see the lists that you’re subscribed to or all public lists on the server. To access the Subscriber’s Corner screen, simply click Subscriber’s Corner on the Toolbar. (For more information on the Subscriber’s Corner screen, see Section 3.3 The Subscriber’s Corner.) To display the lists that you are subscribed to, click the Show All Lists drop-down menu and select Show Subscribed Lists Only. Next, to compose and send a message to the list, click the Post option next to the list name (this option is located on both tabs). The Send Message screen opens (shown in Figure 3-5), which is where you compose your plain text, HTML, or multi-part messages. See below for information on the Send Message screen.
Fill out each of the data entry fields, and then click the [Send] button.
The following fields are available:
Your Name – Enter your name as you wish it to appear in the From field of the email header of the message. The email address that will be used in the From field is the one that is logged into LISTSERV and may not be changed.
To – This line is automatically filled out with the name of the LISTSERV list to which your message will be sent. If you want to receive a copy of your post at the email address listed, then check Send copy of message to.
Topic – Select the topic, if any, that you want to apply to your message. This option will only be shown if topics are enabled for the list.
Subject – Enter the subject line for the email message posted to the list.
Content-Type – Use the drop-down menu to select the format of your email message. You may select Plain Text or HTML.
Plain Text – To add a plain text message, type directly into the text box or copy and then paste your text into the text box.
HTML – To add an HTML message, click the [Upload HTML] button. This will start an applet that will allow you to browse for your HTML file and then automatically upload it along with any inline image files. If your HTML file contains links to remote image files, the applet will check them for errors. After the upload is complete, your message will be displayed as HTML code in the text box. Any inline files will be displayed as attachments. To add an HTML message without using the upload applet, select HTML from the Content-Type drop-down menu. Next, copy and paste your HTML source code into the text box.
Add Part – Click the [Add Part] button to compose a multi-part message. Multi-part messages usually have a plain text part and an HTML part. To build a multi-part message, select the content type of the first part of your message. Next, add the first part by one of the methods described above. Click the [Add Part] button to open a second text box. Select the content-type of the second part and then add it to the second text box.
Advanced – Use the [Advanced] button to display a drop-down menu that can be used to select the charset (character set) of the message. If your message requires a charset that is different from the default charset for LISTSERV (American charset US-ASCII), then you can use the drop-down menu to select the matching one before you type or paste in your message. This selection will not translate one charset to another. It is used to sync the charset of the original message with LISTSERV so that it can be encoded correctly for sending.
Attachments – Use the [Browse...] button to find your file on a local drive. Click the [Attach] button to attach your file to your outgoing message.
Note: Each list can have its own rules for accepting or rejecting messages with attachments. The [Browse...] and [Attach] buttons will function regardless of individual list settings. As a result, your message may be rejected or stripped of its attachment by the list. Be sure to check with the list owner if you have any questions.
Figure 3-5 Composing a Message
3.5.2 Using Email to Post a Message
To send mail to the list by using your email client program, simply compose a message and address it to the list address in your email client. The list address is the one that sends mail to the list moderator, if there is one, or directly to all the other subscribers. List addresses are formatted with the name of the list followed by the domain address (e.g. listname@someserver.com).
