the outbox messages were deleted automatically before, too =)
correct.
well, the outbox itself should not really be used much, as it is only for a "erm, did I sent this to him/her?" or "what did I write" thingy.
mainly for me to have copies in case somebody accuses somebody of something and all mails got deleted.
that is a PITA.
how about paging?
or well...
the outbox might be slow, that's correct. though that saves space.
though if you hit it, you slow others down because the database processes your request... HMMM
tight situation.
