DynDns and Ubuntu 7.10/8.04LTS

[BeNe]

I also use DynDNS and it works!
First - you must be sure that the Posfix Config is the default ispCP Config.
Because you said that you use Usermin or something.
Set the Domain to your DynDNS domain.

You can enable MX in your DNS Account. Problem is only that the IP is dynamic and most Provider set is as default as SPAM or block it. So best way is to use an Relay.
