General Options

After you have login to Mailman list administration page, the General Options page will be displayed by default.

Mailman 2 List administration General Options page
 

On this page you can customize a variety of settings. After you make any desired changes, you must click the Submit Your Changes button at the bottom of the page for the changes to be saved and to take effect.

The following is a brief description of the most commonly used options available from this page. You can read additional details about each option by clicking the blue (Details for ...) link that appears below each description, or reading the knowledge article Mailman List Configuration Options.

  • Public Name: This option allows you to change how the name of your list will be displayed publicly. You can use this option to change capitalization (e.g. capitalizing an acronym).
     
    Important
    Do not change the spelling of the list name. The mailing list will not function correctly if the list name is changed.
  • List Administrators: Individuals listed here have complete control over all parameters of the mailing list. To add new administrators, enter each administrator's email address on a separate line.
  • List Moderators: Individuals listed here have a more limited set of permissions than list administrators, but are allowed to process pending administration requests, dispose of held postings, and perform other functions. To add new moderators, enter each moderator's email address on a separate line.
     
    Important
    In order to split the list ownership duties into administrators and moderators, you must provide the email addresses of the list moderators and set a separate moderator password. Refer to the Passwords section below for instructions on creating moderator passwords.
  • Identifying phrase (a terse phrase identifying this list): Use this field to type a brief description of the list. This phrase is displayed next to the list name on the public page of available list, if the list is public, as well as in email headers.
  • Introductory Description: This field allows you to type a longer description of your list. This description will be included on the top of the General List Information page.
  • Subject Line Prefix: This text will be added to the subject line of messages posted to the list to help distinguish mailing list messages in mailbox summaries.
  • Hide Message Sender: This option allows you to hide the sender of a message, replacing the sender's information with the list address.
  • Discard held messages older than this number of days. Use 0 for no automatic discarding: This options determines how long the list will hold a message for approval by list owners or moderator before the list will automatically delete it. The default for new lists is 90 days, older lists may have this set to 0. This should be adjusted to suite the use-case of the list; however, it is strongly recommended to not set this to 0.

Passwords

Click the Passwords link at the top of the page to view password options. The Passwords page allows you to change passwords for list administrators, and list moderators. List administrators have complete control over all parameters of the mailing list. List moderators have more limited permissions than list administrators, but are allowed to perform pending administration requests, dispose of held postings, and perform other functions.

Change List Administrator Password

To create, or change the list administrator password do the following:

  1. Type the password into the Enter new administrator password field.
  2. Retype the password into the Confirm administrator password field.
  3. Click the Submit Your Changes button.

Change List Moderator Password

To create, or change the list moderator password do the following:

  1. Type the password into the Enter new moderator password field.
  2. Retype the password into the Confirm moderator password field.
  3. Click the Submit Your Changes button.

Membership Management

Warning

It is strongly recommended to not manually add, or remove members from a dynamic mailing list. If you do so the next time the list's membership is automatically updated the change will most likely be undone (i.e. a person removed will be added, or a person added will be removed). All dynamic mailing lists have their membership updated nightly.

Click the Membership Management link at the top of the page to view the options for managing the membership for your mailing list. Four sub-menus are displayed beneath the Membership Management link: Membership List, Mass Subscription, Mass Removal, and Address Change. Each of these three menu options are described below in more detail.

Privacy Options

Mailman's Privacy options section allows list owners/administrators to manage each list's subscription and membership policy. From these pages owners are able to adjust list options to manage member subscription rules, as well as sender, recipient, and spam filters. There are many settings available and going through all possible options is beyond the scope of this guide; however, we'll cover the most commonly used options.

Subscription Rules

Mailman's Subscription rules section allows list owners to configure subscription and membership restrictions, as well as determining whether the list is public or not.

  • Advertise this list when people ask what lists are on this machine? - setting this option to No will hide the list from the server's public display of available lists, setting the option to Yes will result in the list being displayed. Regardless of which setting is chosen, individuals will still need to subscribe to the list, this simply determines how easy it is for people to find the list.
  • What steps are required for subscription? - There are three options available
    • Confirm - This option sends an email with a unique subscription request to the individual's email address asking them to confirm they want to be a member of the list. They must reply in order to subscribe. This helps prevent mischievous (or malicious) people from creating subscriptions for others without their consent.
    • Require approval - This option requires list administrator(s) to approval all subscription requests.
    • Confirm and approve - This option requires both the subscriber to confirm, and the list administrators(s) to approve the request.
     
    Selecting either Require approval or Confirm and approve is strongly recommended.
  • List of address (or regexps) whose subscriptions do not require approval - If the Require approval option is enabled, addresses or regular expressions listed here are allowed to subscribe without administrator approval.
  • Is the list moderator's approval required for unsubscription requests? - Specifies if the list moderator, or owner, approval required for unsubscription request. Selecting No is strongly recommended.
  • List of addresses which are banned from membership in this mailing list - Specifies addresses, or regular expressions, which are banned outright from subscribing to the list with no further moderation required.

    If the intended audience/membership of the list are solely individuals affiliated with the University of Alaska system you can add the following filter rule which will ban all non-UA email addresses from being allowed to subscribe to the list. This will help reduce the amount of undesirable subscription spam to the list administrators/moderators.
     
    ^(?!.*@(.*\.)?alaska\.edu$)
  • Who can view subscription list - There are three options available, when set determine who is able to see the list's membership roster.
    • Anyone - If this is selected, then the list membership is completely public and can be viewed by anyone.
    • List members - Only individuals that are members of the list can see the list membership
    • List admin only - Only list administrators can view the list membership
     
    Selecting either List members or List admin only is strongly recommended.
  • Show member addresses so they're not directly recognizable as email addresses - Enabling this option causes member email addresses to be transformed when they are presented on list web pages (both in text and links), so they're not trivially recognizable as email addresses. This is intended to help prevent the addresses from being harvested by automated web scanners used by spammers. Selecting Yes is strongly recommended.

Sender Filters

When a message is posted to a list, a series of moderation criteria can be applied to determine the disposition of the message. This section contains the moderation controls for postings from both members, and non-members.

Member postings are held for moderation if their moderation flag is set. You can control whether member postings are moderated by default or not

Non-member postings can be automatically accepted, held for moderation, rejected (bounced), or discard either individually or as a group. Any posting from a non-member who is not explicitly accpeted, rejected, or discarded will have thier postings filtered by the general non-member rules.

Member Filters
  • By default, should new list member postings be moderated? - When a new member is subscribed, their initial moderation flag takes its value from this option. Turn this option off to accept member postings by default. Turn this option on to moderate member postings. Moderation setting for individual member's can be adjusted under membership management.
  • Ceiling on acceptable number of member posts, per interval, before automatic moderation (aka member_verbosity_threshold) - If a member posts this many times, within a period of time the member is automatically moderated. To disable this option, set the value to 0. Be careful when using this setting, if set too low this could be triggered by a single message sent to multiple lists (i.e. cross-posted).
  • Number of seconds to remember posts to this list to determine member_verbosity_threshold for automatic moderation of a member - If a member's total posts to all lists on the server with member_verbosity_threshold enabled reaches this list's member_verbosity_threshold, the member is automatically moderated on this list.
  • Action to take when moderated member posts to the list - There are three options available for list members who post while they're moderated.
    • Hold - Holds the message for approval by the list moderators. It is recommend to set this value.
    • Reject - Automatically rejects the message by sending a bounce notice to the post's author.
    • Discard - Discards (i.e. trashes) the message with no notice sent to the post's author.
Non-member Filters
  • List of non-member addresses whose postings should be automatically accepted - If messages will be sent to the list from email address(es) which are not members of the list on a frequent basis which should be approved (i.e. from a UAA department account), adding the address to this field will ensure the message is delivered without requiring the admin, or moderator having to approve the posting each time. Addresses should be added one per line.
  • List of non-member addresses whose postings should be immediately held for moderation - If messages will be sent to the list form email address(es) which are not members of the list, and the list owner/moderator wants to review the message before allowing the content to be passed on, adding the address to this field will ensure the list moderator will be able to review the post. Addresses should be added one per line.
  • Action to take for postings from non-members for which non explicit action is defined -
    • Accept - Message(s) will automatically sent to the mailing list.
    • Hold - Message(s) will be held for approval by list admin or moderator.
    • Reject - Message(s) will be automatically rejected by sending a bounce notice to the post's author.
    • Discard - Message(s) will be automatically discard (i.e. trashed) with no notice sent to the post's author. Selecting the Discard option for non-member posts is strongly recommended
  • Should messages from non-members, which are automatically discarded, be forwarded to the list moderator - List moderators can be informed of non-member posts which are automatically discarded by selecting Yes; however, while this will keep the amount of spam sent to the list low, it will mean that list moderator(s) will receive a copy of each potentially spam posting. It is strongly recommended to set this to No after the list administrator has confirmed the list is configured as desired.

Recipient Filters

  • Must posts have list named in destination (to, cc) fields (or be among the acceptable alias names, specified below)? - Many spam messages use a variety of methods for avoid detection. Setting this value to Yes is strongly recommended.
  • Ceiling on acceptable number of recipients for a posting - Each list has a limit to the total number of recipients associated with a message as an anti-spamming measure. The mailing list itself counts as one address. The default limit is 10, if destination address count exceeds this value the message will be held for moderation. In most cases 10 is a reasonable value. See the Mailman Notice - Too Many Recipients KB article for more details.

Log Out

To logout of the mailing list configuration page, click the Logout button. The Logout button is located at the top of the page under Other Administrative Activities.

Retiring/Deleting a List

  1. Login to the list's admin page.
  2. Under the Other Administrative Activities section click Delete this mailing list (requires confirmation).

  5. For the Also delete archives? question select Yes.
  6. Click Delete this list.
