There isn't really any way to do that within the system.  But if there
are notebooks kept for the "missing days" in question, you could get the
missed messages from there and compose a new message containing them,
then send that to the list.

Actually, my situation is since I merged two lists together, nobody got
the messages. After I fixed the problem. I want to request all messages
form the missing days
