Can´t receive Mails in trunk #639 ?!

[BeNe]

Hello,

i tested the trunk #639 and i am not able to receive E-Mails.
The E-Mail always comes back:

Code:

This is the mail system at host mydomain.tld

I'm sorry to have to inform you that your message could not
be delivered to one or more recipients. It's attached below.

For further assistance, please send mail to postmaster.

If you do so, please include this problem report. You can
delete your own text from the attached returned message.

                   The mail system

<test@mydomain.tld>: unknown user: "test"

But there is a user test@mydomain.tld on my System:

Code:

# cat /etc/postfix/ispcp/aliases

# MTA Managment Virtual Aliases List;
#
# Please do NOT edit it manually;
#
test@mydomain.tld      test@mydomain.tld

Here is the mail.log:

To send e-Mails is no problem!
I don´t understand why only "test" is checked and not "test@mydomain.tld"
