I don't use dyndns (but I do use a similar service from no-ip), but where
does port 52525 come from? Other email systems will expect to use port 25,
which is the standard for SMTP (e-mail). Does your ISP block port 25? Some
do, in which case you are stuffed and will not be able to use your server to
handle incoming email for your domain.

I sugget you change back to port 25. Ensure that everything works internally
on your LAN and only then worry about getting it to work for incoming
emails. Be aware that for outgoing emails you are probably better off using
your ISPs SMTP server because many servers will reject emails from servers
with dynamic IP addresses.

Hope this s.
