You can only cancel your own 12 messages. The superuser can cancel any message. 13 An attempt to cancel a message will fail 14 if the message has already been sent (of course), or if a delivery attempt is 15 currently in progress. Because a delivery attempt is usually started as soon 16 as an E-mail message is added to the mail queue, 17 a cancellation attempt is only effective if the message 18 cannot be immediately delivered for some reason, or if the system 19 is very busy and is working on a mail backlog. 20 <span class="command"><strong>cancelmsg</strong></span> works by marking all pending recipients as 21 undeliverable. A non-delivery report is then generated and sent in the normal 22 fashion.</p><p> 23 <em class="replaceable"><code>msgid</code></em> is the message queue id that can be obtained 24 from the 25 <a class="ulink" href="mailq.html" target="_top" shape="rect"> 26 <span class="citerefentry"><span class="refentrytitle">mailq</span>(1)</span> 27 </a>, 28 command.
