That is added by:

smtpd_sasl_authenticated_header = yes
You can use a header check rule to rewrite the header, somthing like this:
header_checks = pcre:/etc/postfix/header_checks
# vim /etc/postfix/header_checks
/^Received: from (.* \([-._[:alnum:]]+
\[[.[:digit:]]{7,15}\]\)).*\(Authenticated sender: ([^)]+)\).*by
(mail\.example\.com) \(([^)]+)\) with (E?SMTPS?A?) id ([A-F[:digit:]]+).*/
REPLACE Received: from [127.0.0.1] (localhost [127.0.0.1]) by Authenticated
User (mail.example.com) with $5 id $6
And then, in SA local config I used:
# vim /etc/spamassassin/20_smtp_auth_user_checks.cf
header SMTP_AUTH_LOCAL_RCVD Received =~ /Authenticated User
\(mail.example.com\).* /
And then you local score this rule:
# vim /etc/spamassassin/50_local_scores.cf
score SMTP_AUTH_LOCAL_RCVD -4 -4 -4 -4
Hope this helps.
