Wrong steps.  That's not a good way to do it.

Use IMAP.

a) Connect as an admin (with permissions on both user.A and user.B)

b) CREATE user.B.Recent

c) SELECT user.A
d) UID COPY 234,235,236 user.B.Recent

e) SELECT user.A.Drafts
f) UID COPY 12:* user.B.Recent

------------

Much cleaner, and you get all the locking goodness of doing it the
RIGHT way.

An alternative to being admin is just adding read ACLs for user
B on user A's folders (as user A), then logging in as user B and
doing these steps.

You can use any IMAP client library.  We use Perl Mail::ImapTalk,
but whatever language you're familiar with is fine.
