+/** \ingroup msg_task_usage
+ * \brief Deprecated function that used to receive a task from a mailbox from a specific host.
+ *
+ * Sorry, this function is not supported anymore. That wouldn't be
+ * impossible to reimplement it, but we are lacking the time to do so ourselves.
+ * If you need this functionality, you can either:
+ *
+ * - implement the buffering mechanism on the user-level by queuing all messages
+ * received in the mailbox that do not match your expectation
+ * - change your application logic to leverage the mailboxes features. For example,
+ * if you have A receiving messages from B and C, you could have A waiting on
+ * mailbox "A" most of the time, but on "A#B" when it's waiting for specific
+ * messages from B and "A#C" when waiting for messages from C. You could even get A
+ * sometime waiting on all these mailboxes using @ref MSG_comm_waitany. You can find
+ * an example of use of this function in the @ref MSG_examples section.
+ * - Provide a proper patch to implement this functionality back in MSG. That wouldn't be
+ * very difficult actually. Check the function @ref MSG_mailbox_get_task_ext. During its call to
+ * simcall_comm_recv(), the 5th argument, match_fun, is NULL. Create a function that filters
+ * messages according to the host (that you will pass as sixth argument to simcall_comm_recv()
+ * and that your filtering function will receive as first parameter, and then, the filter could
+ * simply compare the host names, for example. After sufficient testing, provide an example that
+ * we could add to the distribution, and your first contribution to SimGrid is ready. Thanks in advance.
+ *
+ * \param task a memory location for storing a #m_task_t.
+ * \param alias name of the mailbox to receive the task from
+ * \param host a #m_host_t host from where the task was sent
+ *
+ * \return Returns
+ * #MSG_OK if the task was successfully received,
+ * #MSG_HOST_FAILURE, or #MSG_TRANSFER_FAILURE otherwise.
