Hi,

First of all it seems that your search domain is:

inovuus.com

This is why it s adding this up in the end. But later since it points to your external address it can not nat the contents to the intranet address and you cant get a response.

First of all the first one is a DNS issue so that it resolves the name adding the local search domain. But as soon as you're trying to reach your  external address you can not get a respons this is normal. If you are not able to fix your hostanme and you still want to check your emial server then you can enter your mail hosts internal adress in youutt hosts file and try to telnet it after this.

Cheers,
K.
