You can't really make those assumptions, though I guess they may

If you're not subscribed to wine-devel your mails will go through
moderation, which means they won't come through until a moderator
looks at them. If you *are* subscribed mail should generally arrive
within a couple of minutes, if it doesn't something is wrong
somewhere.
