.vitem &*queue*&&~=&~<&'text'&>
This modifier specifies the use of a named queue for spool files
for the message.
+It can only be used before the message is received (i.e. not in
+the DATA ACL).
This could be used, for example, for known high-volume burst sources
of traffic, or for quarantine of messages.
Separate queue-runner processes will be needed for named queues.
