Hello again,

Yes, my server's IP is defined in trusted_networks.

AFAIK, SA can't difference beteween SMTP authenticated user and not one.
Postfix, receives the message and is saved on the "Hold" queue; then
MailScanner gets it and analises the message with SA (that sees that the
 client's IP is not in the TXT record of the domain, so it adds SPF_FAIL
score). Am I right?
