Running a mailserver on a dynamic IP-address is difficult at best, but I guess it could work if your dyndns stuff is working.
Pardon!?... being doing this for a long time without major issues using DynDNS and setup is no more or less difficult than with a static address. It is an absolute must if you are running a personal mail server on an external network link which assigns IP addresses via DHCP. However, for a business setup it is probably worth while going for a static IP address for that sort of external connection. BTW it is probably worthwhile but not essential to put the mail server behind some sort of firewall setup (as you have), and setting up a cache DNS. For outgoing relay one would normally use your ISPs mail server, (or an independent smtp server in which case outgoing port info would usually need to be changed as many ISPs block outgoing port 25 traffic from anything but their own mail servers). Main issue with ISP smtp services is usually authentication.
Your alias problem - well, somehow you didn't set it up correctly :-) What was the bounce reason you got? Where did you set up the alias?
External mail - are you using your ISPs mailserver to relay through or are you sending directly? I.e. have you set relayhost in your postfix config? Do you see the mail being delivered? (check your log).
