[Postfixbuch-users] Mails können nicht nach außen versandt werden, warum?

[Andreas Günther]

Hallo,

ich bräuchte Euere Unterstützung auf dem Server mit folgender Konfiguration:

postconf -n

alias_maps = hash:/etc/aliases
biff = no
canonical_maps = hash:/etc/postfix/canonical
command_directory = /usr/sbin
config_directory = /etc/postfix
daemon_directory = /usr/lib/postfix
debug_peer_level = 2
defer_transports =
disable_dns_lookups = no
home_mailbox = Maildir/
html_directory = /usr/share/doc/packages/postfix/html
inet_interfaces = all
mail_owner = postfix
mail_spool_directory = /var/mail
mailbox_command =
mailbox_size_limit = 0
mailbox_transport =
mailq_path = /usr/bin/mailq
manpage_directory = /usr/share/man
masquerade_classes = envelope_sender, header_sender, header_recipient
masquerade_domains = tmx.de
masquerade_exceptions = root
message_size_limit = 10240000
mydestination = $myhostname, localhost.$mydomain
myhostname = tmx.server4you.de
newaliases_path = /usr/bin/newaliases
queue_directory = /var/spool/postfix
readme_directory = /usr/share/doc/packages/postfix/README_FILES
relayhost =
relocated_maps = hash:/etc/postfix/relocated
sample_directory = /usr/share/doc/packages/postfix/samples
sender_canonical_maps = hash:/etc/postfix/sender_canonical
sendmail_path = /usr/sbin/sendmail
setgid_group = maildrop
smtp_sasl_auth_enable = no
smtp_use_tls = no
smtpd_client_restrictions =
smtpd_helo_required = no
smtpd_helo_restrictions =
smtpd_recipient_restrictions = permit_mynetworks,reject_unauth_destination
smtpd_sasl_auth_enable = no
smtpd_sender_restrictions = hash:/etc/postfix/access
smtpd_use_tls = no
strict_rfc821_envelopes = no
transport_maps = hash:/etc/postfix/transport
unknown_local_recipient_reject_code = 550
virtual_alias_maps = hash:/etc/postfix/virtual_alias_maps

access:
ralf at tmx.de             OK

presse at tmx.de                   OK

hs at tmx.de                       OK
tmx.de                          OK

virtual_alias_maps:
tmx.de                  anything
ralf at tmx.de             ralf
presse at tmx.de           tina
hs at tmx.de               horst

Kann ich zwar als besagter User an einen anderen User auf dem Server mailen, 
aber ich kann nicht nach außen zum Beispiel an mich mailen.


Was mache ich hier noch falsch?

Grüße
Andreas
