You may log into WHM and click on "Mail Queue Manager" under the Email grouping.

If you wish to do this through SSH, you may issue the following commands:

exim -bpc (outputs a number which is the current messages in queue)
exim -bp (outputs the full list of messages)

To see the contents of an email, you can use:

exim -Mvl (shows the message log)
exim -Mvb (shows the message body)
exim -Mvh (shows the message header)


1) single message

exim -Mvl 1I7WhH-0003Ce-3B
