HI Marvin,

EXT ISA >> DMZ (SMTP RELAY) >> INT ISA >> INTERNAL EXCHANGE.

ENIC = External Nic card
INIC = Internal Nic card

ENIC(ISA)INIC >> DMZ >>  ENIC(ISA)INIC >>  INTERNAL EXCHANGE
198.162.0.50(ISA)198.162.100.100 >> DMZ(192.168.100.50(SMTP RELAY)) >> 
198.162.100.101(ISA)198.162.0.200 >>  INTERNAL EXCHANGE

So, if you understand the break down of above then it's simple
External ISA publishes to 192.168.100.50 you can use the exchange publish 
function to publish to the SMTP relay server.
the SMTP REALY MACHINE uses [198.162.0.101] as the smart host.
the internal web machine publishes the internal exchange machine.  All my 
mcahines in the DMZ reside in thier own work group 
SMTPCRED.EXE points to 198.162.0.100(EXTERNAL ISA)

Thank you,

Joseph

  Hmmm.this is exactly what I'm looking to do. I have the same setup except the 
SMTP, or exchange, server isn't in a DMZ nor is the web server running the SMTP 
service. Instead it sits in its own Workgroup. 

  My understanding was that the Smarthost needed to be the internal mail 
server. Am I right in guessing that since the ISA server is acting as an SMTP 
relay server, it therefore should be used as the smarthost? 

  I also now have a protocol rule for this server allowing outbound access on 
port 25. 

  SMTPCred was configured to point to the ISA server from the web server but 
I'm not able to connect to the ISA server. 

   

  Hmph!
