Setting List-Server Security
You can use the Security tab to determine whether you want the list-server mailing list to be moderated or unmoderated, and to set access to the list.
- In the right panel, click the Security tab. The Security options appear as shown below.
- Select the following options you want to use.
- Allow posting by. Determines who can post mail to the list.
- Anyone lets anyone on the Internet post mail.
- Subscribers lets only subscribers post mail.
- Moderator lets only the list owner post mail. Select this when you want the list owner to review all messages before they are posted to the list.
- Allow List Unsubscribes based on Subject line. When a user wants to unsubscribe from the list, most list servers expect the Unsubscribe command to be specified in the body of mail message. If you want the list to also accept an Unsubscribe command specified in the Subject line of the message, select this option. When selected, the list will accept the following commands in the Subject line to unsubscribe: unsubscribe, remove, signoff.
| Note: We recommended that you enable this command, but do not advertise that the list server supports it, because these messages are sent to the list address and will go out to the list if the command is misspelled. |
- Disallow Subscriptions. Rejects a Subscribe request, requiring users to be added in one of the following ways:
- By using IMail Administrator to edit the user's file
- By the list administrator through Web Messaging
- By the list administrator through the Remote Administration utility on the web.
- Note that Unsubscribe requests cannot be disabled.
- Disable List Command. A user can obtain a list of the users subscribed to a list-server mailing list by addressing a message to the list server (for example, imailsrv@domain.com) and entering the list listname command in the body of the message. If you do not want users to receive a list of the subscribers to your list, select this option. List owners are always able to receive a list of subscribers, even if the Disable List Command is selected.
- Use Password. Select this to require a password for posting to the list. See "Using a Password".
- Enable Posters List. Select this to specify who can post by listing their e-mail addresses in a file. Click Edit Posters to edit the list.
- Edit Kill File. The kill file lets you specify mail addresses or mail hosts that you do not want to accept mail from. To specify a mail address or host in the kill file, click Edit kill file. The file kill.lst opens in Windows Notepad. In the kill.lst file, enter one entry per line in either of the following formats:
- For example, to deny access to the user fred, enter: fred@widget.com
- For example, to deny access to all users from the mail host widget.com, enter: @widget.com.
- For example, to deny mail from any host ending in widget.com, enter @*widget.com. This will reject all mail from widget.com, bluewidget.com, nifty.widget.com, etc.
- The list server checks the incoming message's MAIL FROM: <user@host> line. The list server denies access to any mail address listed in the kill file.
- The kill.lst file resides in the IMail\lists\listname directory (listname is the directory for the particular list) and applies only to the specified list.
- Click Apply to save your changes.
