[Evolution] default mail address

[Mark Kowitz <mark mail rockefeller edu>]

Greetings,

I'm new to evolution so please be kind.  Is there a way to setup a default 
mail domain address within Evolution?  This way all I need to type in is 
the login name of the user I'm sending e-mail to. Once I hit  the tab key, 
then the default mail domain would be added to the login name 
automatically.  Right now I've been typing in the full dns qualified 
address. But other mail clients like Eudora, Mulberry, etc support a 
default mail address. In mulberry, the field is called "Default domain for 
outgoing mail".

Any ideas?
Thanks.
Mark
