hi ! this is the logmessage i get when postfix rejects a sender ip when not found in $mynetowrks
NOQUEUE: reject: RCPT from unknown[192.168.0.29]: 451 4.3.5 Server configuration error; from=<[EMAIL PROTECTED]> to=<[EMAIL PROTECTED]> proto=SMTP helo=<amisdf.sdfsdf.at> Oct 30 12:38:12 smallsau postfix/smtpd[31559]: > unknown[192.168.0.29]: 451 4.3.5 Server configuration error i tested with: mynetworks = mysql:/etc/postfix/mysql.mynetworks.cf and mynetworks = 127.0.0.0/8 ( behaves in the same way ) for testing i did set: unknown_hostname_reject_code = 6663 but the recect-code is not shown .... all-trough, postfix does what is should ( rejecting unknown sender adressen ) ... but i'm confused about the errormessage. if my ip (sender ip ) is added to $mynetowrks everything works as expected... anyone know's what i could made wrong , .... want to see main.cf ?
