The following example shows how to requeue an SMTP mail message
    that is currently holding, using the TCP/IP command SEND MAIL
    (similar to the DCL command ENTRY/RELEASE). You are prompted to
    confirm that you want the mail message requeued.

    $ TCPIP SEND MAIL /ENTRY=828
    _PLUTO$DKD0:[MARLOW]970207015114580_MARLOW.TCPIP_PLUTO;1? y
