  I'm finally getting back to being able to work on this, since I've been traveling for
work a lot lately. i had a few questions.

  So, I assume by NOT putting Pinecam.com here, it will prevent attempts at local delivery
of pinecam.com addresses. The trouble is, the server really IS named pinecam.com, so it
sounds like I'll need to add a CNAME entry for something else, so I can use the CNAME
here, right? how different does the CNAME need to be, could it be mail.pinecam.com, or
does it have to be fully out of the pinecam.com domain? I don't know how exim performs its
local delivery matching here.

  We seem to be ok there.

   I don't think that's accurate, is it? Google doesn't control the pinecam.com domain, so
there's no way it can publish SPF records under it.

  I control the SPF records, and I have added both Google's outbound MX'es and our own
internal server as permitted senders.
