E-mail app "send queued messages" missing?


I can't seem to figure out how to SEND the "queue" messages in
the e-mail application, - like in Eudora or others - where you
can either set "immediate send" or "queue for later delivery"
(like when you are on the airplane or by the pool, or whatever)
does anyone have a 'fix' or a 'workaround' for this? -
is it, perhaps, fixed in 10.1? - does anyone know?

There is an obvious folder for "To Be Sent" - but I find no
place to actually SEND those messages - once connected
to the network?
