You can use the netstat command (netstat -abn would be a good start) to check that Exchange is in fact listening on port 25, but I imagine it's probably being blocked by the firewall - are you checking using telnet from the server itself, elsewhere on your network, or outside? On sbs2011 you'd not normally manually need to add firewall exceptions for Exchange - have you run the "connect to the internet" and "choose my internet address" wizards from the SBS console home page?
