Setting up the SmartHost - problems!

Hi there,

I’m currently setting up a new NethServer and somehow it tweaks again.

Basically, I don’t have a fixed IP address (

So far I have just entered the data from my SMTP relay into my DynDNS and email worked.

Last night I wanted to set up the new server accordingly, entered the data under SmartHost - but I cannot save the values …
The save button remains inactive

Is such behavior known?

Are there any other better options?
In the admin manual it is currently said that you should only send via SmartHost in an emergency …


I think you need to send a test mail to enable the save button.


See the wiki for more information and how to setup a mail server.
