Anyone know how to set this up from scratch after the ISA 04 box and Exchange 03 box are up and running?
I've tried and can't get mail to flow.
I cannot get my test lab configured to use SMTP at all...I'm so lost!
w2k3 ad domain
2 DCs - both with DNS installed
1 ISA 2004 - connected to the internet fine...clients connect to internet fine.
1 Exchange 2003 - internal mail works fine
I have updated the MX records and A records for the domain to point to mail.domain.com and have set the IP to the external IP of the ISA server.
I have used the mail publishing wizard in ISA 2004 and set the IP to publish as the internal IP of the Exchange server, and set it to receive from external and internal.
No mail goes outbound or inbound. I can however telnet into the external IP of the ISA server to port 25, but even then I can't send mail to internal.
PLEASE HELP. IS THERE A BASIC WALKTHROUGH of how to do this as a brand new install or scenario?
