What problem would this solve? If you need the client certificate
fingerprint consider the following:
/etc/postfix/main.cf:
smtpd_data_restrictions =
check_ccert_access pcre:/etc/postfix/add_fprint_header.pcre
/etc/postfix/add_fprint_header.pcre:
/^(.*)$/ PREPEND X-TLS-Client-Fingerprint: ${1}
Additional information is recorded in Received headers when
$smtpd_tls_received_header=yes.
