What exact username are you using for "this" user?  Is it "test" or
"t...@something.com".  Chances are that postfix is using just the
username part, and you're testing with u...@domain (or vice-versa).

Make sure that maildrop is configured to use the courier authlib
service that you are testing with authtest.  You should see something
similar to this:

centos47[r...@mail1 ~]# maildrop -v
maildrop 2.0.4 Copyright 1998-2005 Double Precision, Inc.
GDBM extensions enabled.
Courier Authentication Library extension enabled.
Maildir quota extension enabled.
This program is distributed under the terms of the GNU General Public
License. See COPYING for additional information.

If yours says Courier Authentication Library extension is enabled,
then maildrop is fine.  If not, then you need to rebuild maildrop
properly (most likely, you're building the wrong version of
maildrop...yes...I did it too).

After verifying that maildrop is configured to get its user info from
courier-authlib, try delivery from the commandline with both user
names I mentioned above.  Take any simple message and pipe it to
maildrop with a high verbose level.  Compare the different results
between the two, and figure out what postfix is doing different than
what you think it should.  Then fix postfix.
