Hello I've got an exchange 2003 server,working on  a dynamic ip adress (yep, i'm poor) ,I've got the receiving of email going through DynDns.org. That's going great rerouting to port 52525 and opening my router on that port and having smtp listen on same port. For the Outgoing, well, ican't seem to put my finger on it, i want exchange to send the mail to my isp smtp server on their port 25. Where and how do i pull this one off? Done it on other mail systems but i'm new to exchange 2003.

What router do you have?  Some Internet firewall/routers allow port-address translation (PAT) where an incoming port 52525 on the outside can redirect to port 25 on the inside, meaning you wouldn't have to change your SMTP server configuration at all.  A PIX can do this, for example.

I assume you're using an alternate port because your ISP blocks port 25.  If that's the case, then outbound won't work on port 25 any better than inbound will.  DynDns.org also has a MailHop Outbound service that will accept your email relays on whatever port you want, specifically to address this issue.
