No INcoming mail

OldSchool
I do not have the SMTP proxy option, so I want just be able to open smtp port (25) on the UTM 425 and send mail straight through to my exchange 2003 server. I can send mail out of that server, ever mail that is coming in it port blocked, the live log show everything is red, therefore being dropped out. 

I have made rules to allow email traffic, and smtp traffic to my inter IP email server. 

any ideas?

    You need a DNAT rule to allow inbound traffic on port 25 to be NATted to the internal IP of your Exchange Server.
