That's Viktor's suggestion, 1000 (or any other val) is fine with me.

But I didn't do them. I extended "warn_if_reject" functionality to
add header in the mail.

Also, I'm a bit puzzled why I'm getting the same X-Reject-Warning
header several times in one spam:

I have this
smtpd_recipient_restrictions = reject_invalid_hostname reject_non_fqdn_sender
 reject_non_fqdn_recipient reject_unknown_sender_domain
 check_sender_mx_access cidr:/usr/local/etc/postfix/mx_access.cidr
 reject_unknown_recipient_domain
 warn_if_reject reject_non_fqdn_hostname
 check_helo_access regexp:/usr/local/etc/postfix/helo-me
 warn_if_reject reject_unverified_sender
 reject_unverified_recipient permit_mynetworks reject_unauth_destination

And would expect at most 2 X-Reject-Warning headers, one from each
warn_if_reject -- what am I missing?
