postfix - server configuratio error - mynetworks

hi !

this is the logmessage i get when postfix rejects a sender ip when not found in $mynetowrks

NOQUEUE: reject: RCPT from unknown[]: 451 4.3.5 Server configuration error; from=<> to=<> proto=SMTP helo=<>
Oct 30 12:38:12 smallsau postfix/smtpd[31559]: > unknown[]: 451 4.3.5 Server configuration error

i tested with:

mynetworks = mysql:/etc/postfix/
mynetworks =

for testing i did set:

unknown_hostname_reject_code = 6663

but the recect-code is not shown ....

postfix does what is should... but i'm confused about the errormessage.

if my ip is added to $mynetowrks everything works as expected...

anyone know's what i could made wrong .... want to see ?
