Not logfile, rather an additional log entry sent to the syslog mail
log.

What was not clear is whether you're trying to log:
(1). The CNs of certificates of remote SMTP clients from which
your server is *receiving* mail, or
(2). The CNs of certificates of remote SMTP servers to which
your server is sending email.
The "...established from..." context suggests (2), but in that case
there are generally no certificates to log. Have you configured
your server to request client certificates? Why? Is this a
submission service?
What version of Postfix are you using?
