[misterm]

Hello with all, enormous problem with the SPF, an error unexplained to explain

Sep 3 18:22:53 xxxxxxxx postfix/policy-spf[9463]: : Policy action=PREPEND Received-SPF: softfail (skynet.be: Sender is not authorized by default to use 'xxxxxxxx@skynet.be' in 'mfrom' identity, however domain is not currently prepared for false failures (mechanism '~all' matched)) receiver=xxxxxxxx.kimsufi.com; identity=mailfrom; envelope-from="xxxxxxxx@skynet.be"; helo=immoweb.be; client-ip=62.72.106.180

You can m' to help, because I am to embarrass for this error, the question that I pause myself, is this, a problem of the server or l' send message

When does this happen? When you send to another server, or when another server sends an email to your server?
