Virtual Mailbox Postfix

Hello,

Let me ask you if SmartList will work in my Postfix installation. I'm
using postfix with virtual mailboxes, as you can see in the howto i
did used:

http://www.howtoforge.com/virtual_users_and_domains_with_postfix_debian_etch

I'm using Debian and so far i tried to install smartlist package with
"apt" and configure postfix, i couldn't send e-mails to any list
created with smartlist. At main.cf, i made the following change:

virtual_alias_maps = mysql:/etc/postfix/mysql-virtual_email2email.cf,
hash:/etc/aliases

At /etc/aliases,

########################################################################
testlist: "|/var/list/.bin/flist testlist"
testlist-request: "|/var/list/.bin/flist testlist-request"
########################################################################

As i try to send mail to [email protected], i get the response from
[email protected]:

The mail system

<"|/var/list/.bin/flist testlist"@mydomain.br> (expanded from
    <[email protected]>): unknown user: "|/var/list/.bin/flist
    [email protected]"

Well, i just kicked the ball, don't have any idea if it's supposed to
work or not.

thanks,

Paiva
