Hi Glenn,
 
Good ideas. However, when using the split SMTP, its good to treat it the
same as you do your DNS services. Your primary and secondary DNS and
SMTP servers should be hosted by different provides, and preferable in
different regions of the country or world. Check out John Tolmachoff's
offerings, I'm pretty sure it offersing both DNS and SMTP secondary
services.
 
HTH,
Tom

        I think it is a sound configuration that offers many advantages,
mail content filtering for one, Mail queuing for another, if your
internal messaging system goes tits up you can still capture in bound
mail for future delivery, I use a split SMTP design on my network and
there is nothing wrong with it, works great, so have fun.

                Hi all,
                 
                I was wondering: would it be a good idea to install an
SMTP server on the ISA machine itself?
                I want to use the the SMTP filter, and I don't really
have an other server available to install SMTP.
                 
                The situation here is a back to back setup with a Linux
firewall on the "outside" and ISA as the internal FW.  In between them
there's obviously the DMZ.  Mail arrives on the SMTP servers in the DMZ
which do a forward to the (published) exchange server.  Policies are
made so that only the SMTP's from the DMZ can connect to the published
server.
                 
                The new situation would be an SMTP on the ISA itself,
which also can only be contacted by the SMTP's in the DMZ.
                 
                What do you guys think?
