This is simple. Use the mailq command to find the local queue ID of the message. It will look something like:
You can then flush the message with:
sendmail -qIyourqueueID -oTnow
The "I" flag to the -q flag specifies which queue ID to use. The -oTnow flag sets the queue timeout to "now". Note sendmail will still try to deliver the message once when you do this. If this is not OK, then blow the message away with:
But the timeout is much recommended over blowing the message away.
