Sorry I wasn't clear.
 
Mail is flowing from the internal network to the Internet via B2B ISA's
and DMZ SMTP server.  Mail is NOT flowing from Internet to the DMZ SMTP
rely to the internal mail server.
 
Still curious the best way to troubleshoot this.  I did double-check the
server publishing rules and the remote domains config on the DMZ SMTP
mail relay server.  Maybe I'm missing something obvious but can't find
it.
 
Hhmmm....  Any ideas?
 
TIA,
 
Gillian

        Hi Gillian,
         
        So, outbound mail is working? That is to say, mail from the
internal network is finding its way to the Internet?
         
        And, inbound mail from the Internet is not making its way to
your internal network?
         
        Or, is it the other way around?
         
        Thanks!

                Thanks Tom.  Very helpful info and some progress.
But...
                 
                I've now got external mail flowing using the SMTP DMZ
relay server fine but inbound is still not working.  I understand from
your post that external mail flow is from (among other things) the SMTP
Virtual server config and internal mail flow from the Remote Domains
config on the SMTP server.
                 
                What's the best way to troubleshoot this internal mail
flow issue?  I've double-checked the ISA server publishing rules on both
ISA's and they look correct.  I've double checked the Remote Domains
config which forwards to the Internal ISA's external interface.
                 
                So close but yet so far...  :)
                 
                TIA,
                Gillian
