Well as far as I know SMTP is not blocked. I wanted to go through my

I had relayhost set to my ISP, but I musta had something wrong,
because some people would get replies, while other people wouldn't.
Take a look at
http://www.postfix.org/SOHO_README.html
you may want to use smtp_generic_maps to rewrite your dyndns addresses
to those of your ISP.
if you have problems, show output of 'postconf -n' as well as relevant
logs.
PS. do not setup an MX for your domain unless you have a static IP (one
that never changes). otherwise, when the IP is assigned to someone else,
you'll lose mail.
