[Postfixbuch-users] cyrus lmtp

[Flavio Mini]

Hallo,
ich versuche einen E-Mailserver zu konfigurieren. Leider klappt die lokale Zustellung der E-Mails nicht.
Folgende Fehlermeldung:
Jan 29 14:21:55 linuxserver postfix/lmtp[5292]: 64EFA922: to=<root at linuxserver.fmini.com>, orig_to=<root>, relay=none, delay=1970, status=deferred (connect to /var/lib/imap/socket/lmtp[/var/lib/imap/socket/lmtp]: Permission denied)

Die rechte für lmtp sollten in Ordung sein: 
srwxrwxrwx   1 root  root   0 Jan 29 13:48 lmtp

Wie auch für das Vezeichnis:
drwxr-x---   2 cyrus mail  168 Jan 29 13:48 socket

Der Eintrag in der cyrus. conf :
  lmtpunix      cmd="lmtpd" listen="/var/lib/imap/socket/lmtp" prefork=1

meine main.cf:
readme_directory = /usr/share/doc/packages/postfix/README_FILES
mail_spool_directory = /var/mail
canonical_maps = hash:/etc/postfix/canonical
virtual_maps = hash:/etc/postfix/virtual
relocated_maps = hash:/etc/postfix/relocated
transport_maps = hash:/etc/postfix/transport
sender_canonical_maps = hash:/etc/postfix/sender_canonical
masquerade_exceptions = root
masquerade_classes = envelope_sender, header_sender, header_recipient
myhostname = linuxserver.fmini.com
program_directory = /usr/lib/postfix
inet_interfaces = all
masquerade_domains = fmini.com
mydestination = $myhostname, localhost.$mydomain
defer_transports =
disable_dns_lookups = no
relayhost = [smtprelay01.ispgateway.de]
content_filter =
mailbox_transport = lmtp:unix:/var/lib/imap/socket/lmtp
smtpd_sender_restrictions = hash:/etc/postfix/access
smtpd_client_restrictions =
smtpd_helo_required = no
smtpd_helo_restrictions =
strict_rfc821_envelopes = no
smtpd_recipient_restrictions = permit_mynetworks,reject_unauth_destination
smtp_sasl_auth_enable = no
smtpd_sasl_auth_enable = no
smtpd_use_tls = no
smtp_use_tls = no
alias_maps = hash:/etc/aliases
mailbox_size_limit = 0
message_size_limit = 10240000
html_directory = no

Kann jemand mir über diese Hürde hinweghelfen?

Gruß Flavio
