That should work fine, although Sieve won't know the envelope from or
to.  You can easily add the envelope to address on the command line if
you want to use the same one for every message, but adding the envelope
from is a little trickier -- the envelope from isn't standardized in
Maildir, so you'll have to try to pull it from the message headers.

If you want to run sieve on all the messages in an mbox file, you could
use formail from procmail in place of your for loop (e.g. formail -s
deliver < mboxfile.)
