[Dovecot] postfix+dovecat: virtual domains with imap+lmtp

[el07694]

 Hi to all,

 I have tryed a few days to configure postfix/dovecot to run into a VPS 
 machine (CentOs)
 -->The machine has 2 domains (but more in the future)
 -->i want info at mail.domain1.com and info at mail.domain2.com to be 
 seperated mailboxes
 -->i want to use lmtp protocol to connect dovecot with postfix
 -->It will be perfect if i can use the system users for authentication

 I /etc/postfix/main.cf file looks like this

 smtpd_soft_error_limit = 10
 smtpd_hard_error_limit = 20
 masquerade_domains = mail.going-on.com mail.commundi.de
 masquerade_exceptions = root, papinhio
 relocated_maps = hash:/etc/postfix/relocated
 smtpd_client_restrictions = check_client_access 
 hash:/etc/postfix/access
 virtual_mailbox_domains = mail.going-on.com mail.commundi.de
 virtual_mailbox_base = /var/spool/virtual_hosts
 virtual_mailbox_maps = hash:/etc/postfix/virtual
 virtual_uid_maps = static:0
 virtual_gid_maps = static:0
 mailbox_command = /usr/libexec/dovecot/dovecot-lda -f "$SENDER" -a 
 "$RECIPIENT"
 dovecot_destination_recipient_limit = 1
 mailbox_transport = lmtp:unix:private/dovecot-lmtp

 /etc/postfix/relocated file has only comments
 the same for /etc/postfix/access file
 i have made /var/spool/virtual_hosts folder with chmod 777
 inside this folder i have made mail.going-on.com folder and 
 mail.commundi.de folder

 cat /etc/postfix/virtual produce this:
 papinhio at mail.going-on.com mail.going-on.com/papinhio

 papinhio is a system_user!!

 uid,gid = 0 (the root user)

 Ok, the /etc/dovecot/dovecot.conf file looks like this:

 !include conf.d/*.conf
 !include_try local.conf

 protocols = imap lmtp
 service lmtp {
  unix_listener /var/spool/postfix/private/dovecot-lmtp {
    group = postfix
    mode = 0660
    user = postfix
   }
 }


 protocol lmtp {
   mail_plugins = quota sieve
 }



 mail_location = mbox:/var/spool/virtual_hosts/%d/%n


 Both of the services can start this no errors/warnings
 I can send mail from bash with this command : /bin/mail -s "Hello" 
 "el07694 at mail.ntua.gr" < /etc/dovecot/dovecot.conf

 Can anyone help me, plz?
 I don't know what i do wrong

 Thanks in advance,
