Ubuntu server. dynamic IP and blocked ports from ISP


Well I installed the Linux Apache Mysql PHP server of ubuntu 6.0.6.

But due to my ISP I get a new IP every 36 hours. Now I have solved this by having a no-ip account that checks my IP every 5 minutes. And my ISP also blocks every outgoing port under 1024. So I had no-ip redirect port 80 to an other port and this works for Apache.

But now my problems:

1. Pure-ftpd
Installed and works on the local network. But how do I change the config (I know pure-ftpd has no configfile) so that when my server reboots it uses a passive port range and listens on a certain port. Also I am behind a router so I have to fill in my ip to send to the connectors.

2. I would like to have an email server
Now I know I can't send outgoing mail directly but would I forward outgoing mail it to my ISP smtp account. And how do I configure it for incoming mail since my domain is a no-ip domain. (Would like to use postfix or Courier mail server)

So to recap:
ISP blocks below 1024
mydomain.no-ip.org domain
router with NAT

If you could just point me to the right tutorials I'd be thankful. The once i find don't really keep in mind a dynamic ip and blocked ports. (and sorry for the noob questions)

Blocking below port 1024 should not matter becuase you always go out of a port on your computer greater than 1024 anyways. Even when you go to a website you still go out >1024 but when reach the web server then you enter on the servers incoming port 80. As far as forwarding off of your ISP's email I would not do that. They will think you are targeting them to be a relay agent and you might get into some trouble with them.
