XMPP provides the option for servers to store-and-forward IM messages when they sent to a user that
is not logged in. Supporting store-and-forward of 'offline messages' can be a very convenient
feature of an XMPP deployment. However, offline messages, like email, can take up a significant
amount of space on a server. <fmt:message key="title" bundle="${lang}" /> provides the option to handle offline messages in a
variety of ways. Select the offline message handling strategy that best suites your needs.
