I've been doing everything the instructions say http://www.postfix.org/MILTER_README.html and I was able to build, configure and run dkim-filter but postfix doesn't seem to call it.
I've got this in my main.cf
# DKIM milter_default_action = accept milter_protocol = 2 smtpd_milters = unix:/etc/postfix/dkim-filter.sock
and I set dkim-filter to read from that same file descriptor, no errors anywhere, but I don't get any dkim headers in the mail I send through postfix. Is there something else I have to turn on?
This is on solaris 10. postfix 2.3.20060611
