I have just gone from an NT4/Exchange 5.5/Proxy 2.0 Domain to 2003 Server with Exchange 2003 and ISA 2000 however I cannot receive incoming mail from the internet. I can send out without any issues.
My existing Exchange install sits on the same box as proxy 2.0. We have replaced this with a 2003 Exchange Server and ISA Server on a seperate machine.
The ISA Internet facing NIC has the same IP as the previous Proxy 2.0 box so there should be no need to adjust the MX record at the ISP's DNS. As the exchange server is now sitting behind ISA we have configured a forwarder to the Exchange 2003 server from the ISA server so that incoming mail is passed on. We know this works as we can telnet the Exchange server from behind the ISA server without any problems. Our ISP is also able to telnet our exchange 2003 Server without issue.
I am stuck as to what we should try next.
Any help/suggestions would be appreciated.
Thanks,
Barry
