[Evolution] Sender's Hostname

[Jeff Mrochuk <jm v-wave com>]

Is there a way to set senders hostname?  I use a hostname which does not
exist on the net (I'm behind a firewall) therefore when I send a mail I
get rejected unless I can give it a real hostname.  For example in the
mutt config:

set hostname=""

Is there anything like this for evoltion?
