[Dovecot] problem to configuration dovecot and postfix

[Akihiko Sato]

Hi,

I'm having a problem with dovecot and postfix. I'm using a dovecot
version 2.0.13.
Postfix (Version: 2.8.5) config is changed according to the
http://wiki2.dovecot.org/LDA/Postfix:

I have thought to build a virtual user and virtual mailbox, and use
the functionality of the Sieve.
However, when the test set, the mail not received the mailbox. Record
that there was a "temporary
failure" in the log of Postfix.

It delivered and to change the "virtual" to "dovecot", I think that's
a matter of dovecot.

To ensure that mail is delivered as intended, will How do I?
Can anyone give me a hint what to do?
