Well, if you're actually able to send mail from your server then smtp on port 25 isn't blocked.
but if I forward [ outside port 25 > inside port 25 ] then nothing works. Then something else goes wrong ? hmhm

The reason many ISPs block port 25 is to prevent fly by night mail servers that propogate spam. They would prefer if you send mail through their servers so they can track and prevent mass mailings.
yeah that sounds reasonable.
