Pretty much like mine, except I have:
Don't know if the order makes any difference.

I don't have this. What I did was in root's home dir (/root) I created a
file called .forward and put in the following:
postmaster at ci.juneau.ak.us
You might want to add postmaster at woodmaclaw.com as a 2nd email address for
Administrator in Exchange, so that the Exchange server accepts that, or
conversely, put administrator at woodmaclaw.com in your .forward file. Or both
just to be safe.
Might all be much of a muchness, but I know using a forward file works.

That looks fine (assuming that someone actually sends to
someone at www.woodmaclaw.com - I'd expect www to refer to a machine in the
woodmaclaw.com domain rather than a mail domain but there's nothing that
says it can't be both). I also assume that 10.1.1.2 *isn't* the IP address
of mail.woodmaclaw.com, but is instead the internal address of the machine
to forward to.
Did you create the mailertable.db? You have to run the following command
whenever you change a file like access, or mailertable:
makemap hash /etc/mail/mailertable < /etc/mail/mailertable
makemap hash /etc/mail/access < /etc/mail/access
If you don't do that, sendmail will never use the changes. In my
circumstances, the mailertable, access table, etc. are pretty humble, but an
ISP that is hosting hundreds or more domains might have a huge table so
sendmail wants to create a db out of it for better performance. The makemap
command builds the database.
Also, make sure you use tabs, not spaces between the domain name and
> ---------- In my relay-domains I have this....
That looks fine. Or at least it looks similar to mine. This file doesn't
need to be hashed like the mailertable or the access table.
And, in your sendmail.cf you should have the following (I'm assuming you
have an access table - can't recall if you mentioned it or not):
dnl These mailers are available. per default only smtp is used. You have
dnl to add entries to /etc/mail/mailertable to enable one of the other
If you change your sendmail.cf you'll have to regenerate your

I think this is actually OK - it needs to be .com on the outside, but can be
.local on the inside. I was a bit befuddled yesterday by your description.
I think I sorted it out in my mind.

Does the Exchange server accept mail for someone at woodmaclaw.com? It will
need to do that of course.
Beyond that, I can't think of what else might be goofy. Hope this helps...
