List Security

How to get here

Use List Security options to determine whether you want a list to be moderated or unmoderated as well as to determine who has access to the list.

• Allowed Posting By. Select users that can post to the list.
  • Anyone. Select to let anyone with an email account post mail to a list.
  • Subscribers. Select to let only the list subscribers post mail to a list.
  • Moderators. Select to let only the list owner post mail. Moderator is used when you want the list owner to review all messages before they are posted to the list.

Select the options you want to use:

• Allow List Unsubscribes Based on Subject Line. Select this option if you want the list-server mailing list to also accept an Unsubscribe command specified in the message Subject line. When users want to unsubscribe from the list-server mailing list, most list servers expect the Unsubscribe command to be specified in the body of the mail message.

  When selected, the list-server mailing list will accept the following commands in the Subject line to unsubscribe to a list:

  • unsubscribe
  • remove
  • signoff

    Important: If the list requires a password, passwords are case-sensitive and there must be no leading spaces after the password. See example below.

  Example:

  The following example assumes there is a list named beer that allows unsubscribes based on the Subject line on an email domain named domain.com.

  To unsubscribe from the list:

  TO: imailsrv@domain .com

  Subject:Unsubscribe beer

• Disallow Subscription (ie: Private List). Select to reject subscribe requests to a list. List subscribers can only be added one of the following ways:
  • List administrator using IMail Administrator to edit the Users file.
  • List administrator using IMail Web Messaging to change user list permissions.

  When selected, a Subscribe request will be rejected, and users can only be added by using IMail Administrator to edit the Users file

  Note: Unsubscribe requests cannot be disabled.

• Disable List Command. Select if you do not want users to receive a list of the subscribers to your list-server mailing list. If not selected, users can obtain a list of the users subscribed to a list by addressing a message to the list server (for example, imailsrv@domain.com ) and issuing the list [listname] command in the body of the message.

  Note: List owners can always receive a list of subscribers regardless of whether the Disable List Command option is selected and regardless of the list type.

• Enable Posters List. Select to let any user with an email address in the posters' list post to any type of list. If the Use Password option is enabled, users in the posters' list must enter a password.

  The posters' list is stored in a file named POSTERS.LST located in IMail Top Directory\Lists\listname.

• Use Password. Select to require a person to use a password before posting to the list. The password must be the first entry in the message Subject field. The password must be enclosed in brackets and colons. For example, Subject:[:password:]Unsubscribe beer

  The Use Password setting affects different list types as follows:

  • If Use Password is selected for an anyone list (open), all posters are required to enter a password to post to the list.
  • If Use Password is selected for a subscriber list, the subscribers are required to enter a password to post the list.
  • If Use Password is selected for a moderated list, the moderator is required to enter a password to post to the list.
• Posters File. Click this link to view, modify, or enter an email address for users that can post messages to the selected list.
• Kill File. Click this link to view, modify, or enter an email address for users that are no allowed to post messages to the selected list.
• Save. Click Save to apply changes.
• Cancel. Click Cancel to exit without saving changes.
