No on DKIM. Evidently Postfix and DKIM are not playing nicely on FreeBSD 
and would take some hacking. I may switch to Exim where DKIM support is 
easy to configure.

Yes on MTA identification:
  # telnet localhost 25
Connected to localhost.
Escape character is '^]'.
220 lists.c2.social ESMTP Postfix

Google is not blocking our mails. It's Yahoo, Comcast, gmx, etc. They 
seem to rely on Spamhaus.

I'm thinking this may be because the domain is brand new. Teach me to 
"volunteer" my time for an organization.
