Postfix+SpamAssassin. I want a delivery report from the target server, not from Spamassasin. How?

Question

postfix

Good afternoon,
I have Postfix 2.10, spamassassin 3.3.2
Connected spamassasin like this master.cf

smtp inet n - n - - smtpd -o content_filter=spamassassin ... ... spamassassin unix - nn - - pipe user=spamassasin argv=/usr/bin/spamc -f -e /usr/sbin/sendmail -oi - f ${sender} ${recipient}

Clients are set to submit after 25 (not via submission). When sending a letter, with a notification of delivery, spamassasin's whack comes, that everything is fine. Even if knowingly send to nowhere

this is the mail system at host mydomain.tld.
Your message was successfully delivered to the destination(s) listed below. If the message was delivered to mailbox you will receive no further notifications. Otherwise you may still receive notifications of mail delivery errors from other systems.
The mail system
: delivery via spamassassin: delivered via spamassassin service

Is it possible to exclude an IP range, or by sender mask, or otherwise bypass spamassassin? Those. configure content_filter to be applicable only to def. letters (by domain, ip, xs_what)
ps internal_networks , trusted_networks , whitelist_from are specified, but this is not enough. Probably it is necessary to steer by means of a postfix.
