7.5 How can I get Mailman to tell me when my post has been received by the list? (ack option)

On most lists, you will simply receive a copy of your mail when it has gone through the list software, but if this is disabled (See Section 7.4), your list mail delivery is disabled (See Section 7.1), you are not subscribed to that topic (See Section 9.2) or you simply want an extra acknowledgement from the system, this option may be useful to you.

Note: If you are not subscribed to the list, this option cannot be used. You must either check the archives yourself (if the list has public archives), ask someone who is subscribed to the list, or subscribe to use this option.

To set this using the web interface:

  1. Log in to your member options page. (See Section 3.1 for more details on how to do this.)
  2. Look for the section marked "Receive acknowledgement mail when you send mail to the list?" Set it to "Yes" to receive a mail letting you know your post has been received, and "No" to avoid receiving such an acknowledgement.

To set this using the email interface:

  1. Send a mail to with the command set ack on or set ack off.

    Commands can appear in either the body or the subject of the message. (See Section 3.2 for more information about sending mail commands.)

  2. Set it to "on" if you wish to receive mail letting you know your post has been received, and "off" to avoid receiving such an acknowledgement.
