ListProc— List Application

Use this form to request a new list to be created on the centralized list processor known as

Please Note:

  • It will take 1-2 business days to review an application and create a list.
  • This time will increase at the beginning of semesters and if there are errors in the application.

First, we need the e-mail address of the person who will be acting as the primary list owner. This person will have the ability modify the list's configuration, add and remove other list owners, add and remove addresses from the list, receive list errors, etc. This address must be the address that shows up in the From: line when the list owner sends e-mail messages.

Please Note:

  • Only those affiliated with the University of Colorado at Boulder may own a list. This is generally verified by the address given below.
  • Lists should not have more than 200 subscribers, as greater numbers interfere with the functioning of campus systems. Larger subscriber lists must be handled by a private list provider.
  • Your address given below must match your e-mail rewrite at the University.
Primary list owner e-mail address: NOTE: To successfully manage your list, you have to enter your email-address that appears on the From line when you send messages. If your are unsure of how your address appears on the From line, send email to yourself and verify what that address is before submitting the application.

Second, we need a password for the list owners to use to manipulate the list. This should not be a password that is used on any of the list owners' computer accounts. Note: list passwords are case sensitive and may only contain letters and numbers.

List password:

Third, we need the name that you would like to call the list. This will be the address of the list and should be fairly specific but not longer than a few words and may not contain any blanks or special characters other than `-' (dash) and `_' (underscore) and must be 20 characters or fewer. List names are case insensitive, i.e. the list CU-Bungee is equivalent to cu-bungee. You must specify your list name in all lower case. If the list is going to be associated with a particular group or department, we suggest that you follow the guideline of {group/dept}-{list}. For example, all lists for the OIT department are of the form its-{list}, i.e. its-managers. To get a current list of examples of current list names, send the command:


to listproc@lists.Colorado.EDU as an e-mail message. This will return the list of lists to you via e-mail.

List name:

Fourth, we need a short text description of the list that will be used in the list processing software to identify the list. This description cannot be more than 25 characters long and should NOT contain commas.

Short text description:

Fifth, we need a longer text description of the list that will be sent to users who issue the info command. This should explain what the list is about and perhaps policies of the list.

Please Note: Users will not get this information when they subscribe to the list. This information will only be given when the info command is used.

Long text description:

Lastly, we need any special instructions or list features that you would like initially incorporated into your list. Because there are so many list options, only the most common will be outlined below. When requesting initial features, please use the terminology below for clarity. You may request only one feature within each group of features defined below. You may change your list features yourself at any point after the list has been created. In the descriptions below, you may only check one feature per section.

Default List Values

The default values for lists are pre-checked in the sections below.

How Messages are Distributed to the List

unmoderated - Messages sent to the list are distributed automatically.

moderated-edit - Any message sent to the list by other than the list owners will be forwarded to the list owners for approval. The list owners can then edit the message and forward it back to the list or simply forward it along without any editing.

moderated-no-edit - Any message sent to the list by other than the list owners will be forwarded to the list owners for approval. The list owners can then approve the message by using the message tag contained within the message.

How Subscription Requests are Handled for the List

open-subscriptions - Subscription requests for the list are automatic.

owner-subscriptions - Subscription requests for the list are forwarded to the list owners for approval.

Does the List Show Up in the Lists Command?

visible-list - List and its short description show up when a user issues the lists command.

hidden-list - List and its short description do not show up when a user issues the lists command and other commands are limited to only list subscribers.

Who Can Send to the List?

send-by-subscribers - Only subscribers and owners of the list may send to the list.

send-by-owners - Only list owners may send to the list.

Where do Replies to List Messages Go?

With all of the reply features, only the Reply-To: mail header is affected. If a list user's mail program doesn't understand or use the Reply-To: mail header, reply features cannot be guaranteed.

reply-to-sender - Replies to list messages will go back to the original sender.

reply-to-list-always - Replies to list messages will go back to everyone on the list. OIT recommends against using this feature as it may create mail loops.

reply-to-omit - Reply-to: header line is omitted from messages from the list. Replies will depend on the mail program being used. Usually the list owner will receive replies if this option is set.

Does the List Distribute Digests and How Often?

A list digest is a compilation of messages sent to a list during a specific time period that is then distributed to those users who have set their mail mode to digest.

no-digests - All list traffic will be distributed as individual messages.

digest daily hh:mm - Digests are distributed daily at hh:mm, e.g. digest daily 12:00 would mean that a digest would be sent out every day at noon if messages had been sent to the list during the previous day. Enter time in 24 hour Format.

digest weekly day-of-week - Digests are distributed weekly on day-of-week day, e.g. digest weekly wednesday would mean that a digest would be sent out once a week on Wednesday if messages had been sent to the list during the previous week. A digest weekly list must be given a day of the week to send out digests. If you choose this digest option, you must also choose a day of the week.

OIT recommends that you set your list to no-digest initially and then change it if your subscribers request it.

Initial List of Subscribers

If you would like to provide an initial list of subscribers, include them below in the format:

subscriber-address First-Name Last-Name

one per line, e.g.: Ralphie Buffalo Chip Buffalo

Make sure that you enter them one per line with a carriage return after each line.

Because it is very difficult to know the address that the list processor will need to use to verify an address for restricted lists, OIT recommends that you do not provide an initial list and instead let list subscribers subscribe themselves to lists.

Please Note: It is not recommended that you add users in this manner due to email conventions at the University of Colorado. You should have them subscribe to the list individually (a process described when you get your confirmation email).
One problem a lot of people experience when placing addresses in this field is they tend to copy and paste those addresses. That will also copy hidden carriage returns onto the line following the last address. Before submitting, place the cursor on the line following the last address and hit delete a couple of times to remove those hidden carriage returns. If you submit the application and you get an error which states invalid initial subscribers field but it doesn't specifically list any addresses, that is the problem.
Initial Subscribers:

You will be contacted via e-mail when your list has been created. This contact message will include instructions for use and management of your lists.
