This isn't really an issue. There's nothing wrong with using .local.
You still need split DNS for your public domains with most firewalls,
but it has nothing to do with the problem at hand. This isn't creating
any sort of issue that you wouldn't have if you were using the actual
registered domain. You just need an additional zone if your AD domain
isn't the same as your public domain.
Tom goes further into this argument in his ISA 2004 book, but even after
reading that (which, for the most part, is a good book) the argument
doesn't hold water. This is from experience - roughly half of the
domains I administer use .local, with the other half using actual
registered domain names. Neither is better or worse than the other.
You just usually need an additional DNS zone in networks where you
aren't using the company's registered domain name.
To actually address the problem...
I created an A record for
mail.graphicsolutions.com in
my internal DNS, yet when I ping internally it will only resolve
correctly when I ping
mail.graphicsolutions.com.gsi.local
Because you created the A record as
mail.graphicsolutions.com.gsi.local. You need to setup a new zone in
your internal DNS servers for graphicsolutions.com, then add an A record
there for mail. Then it'll resolve as you desire. Alternatively, you
could instead create a CNAME for mail.graphicsolutions.com that points
to your OWA server's internal FQDN (exchange.gsi.local or whatever).
