I am trying to migrate from Desknow to Zimbra as the later seems to be more featured but the MTA issue is driving me nuts.

I am not an expert at Linux by any means so I am doing everything from the Admin console.

I am getting the "...must contain local network interfaces..." error.

I am also using Webmin which lets me see all the network interfaces but still no luck.

Only complicating item is that I have IPv6 installed and running on my LAn so the Zimbra box automatically picks up an addr.

This is probably very simple but I am not seeing it.

Any help would be appreciated.
