versenden von mails / fehler: 504 5.5.2 Helo rejected

[retox]

hallo,

habe die aktuelle version vom 5.10.07 installiert, bei Versand aus dem Webmail (auch per Client) erscheint folgende Fehlermeldung vom Server:

Message not sent. Server replied:

Command parameter not implemented
504 5.5.2 <xxx.xxx.xxx.xxx>: Helo command rejected: need fully-qualified hostname

---------

Server hängt via offizieller IP im Netz, in der /etc/postfix/main.cf steht bei
hostname=mx1.domain.de
mydomain = $myhostname
myorigin = $mydomain


in /etc/hosts ist der hostname auch richtig hinterlegt.
PTR Record für die IP existiert auch...

ein postconf -n sagt:

Code:

alias_database = hash:/etc/aliases
append_at_myorigin = yes
append_dot_mydomain = no
biff = no
broken_sasl_auth_clients = yes

und im Logfile steht folgender Error bei Versand:

Code:

Nov  5 19:01:56 mx1 postfix/smtpd[3350]: NOQUEUE: reject: RCPT from mx1.domain.de.local[127.0.0.1]: 504 5.5.2 <xxx.xxx.xxx.xxx>: Helo command rejected: need fully-qualified hostname; from=<user@name.de> to=<xyz@domain.de> proto=ESMTP helo=<195.95.163.4>

jemand eine Idee?
