[opendmarc-users] Port never opening, connection refused.

[Bruce]

Debian stretch.
Postfix + dkim + dmarc.

Opendmarc is not working.  I'm getting:

      Nov 26 10:36:07 mail postfix/smtpd[30012]: warning: connect to 
Milter service inet:localhost:8893: Connection refused


Relevant configs:

/etc/default/opendmarc


      7 RUNDIR=/var/run/opendmarc
      16 SOCKET=inet:8893 at localhost
      19 USER=opendmarc
      20 GROUP=opendmarc
      21 PIDFILE=$RUNDIR/$NAME.pid
      22 EXTRAAFTER=


/etc/opendmarc.conf

      58 UMask 0002
      59
      60 ##  UserID user[:group]
      61 ##      default (none)
      62 ##
      63 ##  Attempts to become the specified userid before starting 
operations.
      64 ##  The process will be assigned all of the groups and primary

      66 #
      67 UserID opendmarc:opendmarc
      68 Socket inet:8893 at localhost

(I've also tried with umask 007)

/etc/postfix/main.cf

      85 milter_default_action = accept
      86 #milter_protocal = 2
      87 smtpd_milters = inet:localhost:8891 inet:localhost:8893
      88 non_smtpd_milters = inet:localhost:8891 inet:localhost:8893


This is the log entry upon startup:

      Nov 26 10:44:04 mail opendmarc[30162]: OpenDMARC Filter v1.3.2 
starting (args: -p local:/var/run/opendmarc/opendmarc.sock -u opendmarc 
-P /var/run/opendmarc/opendmarc.pid)
      Nov 26 10:44:04 mail opendmarc[30162]: additional trusted 
authentication services: mail.lancasterfungus.com

The port is never created, no listing in netstat.

Can anyone point me in the right direction?

Thanks

Bruce
