Description of Problem:
I'm using NIS in my network to distribute email
aliases so when I send an email to anyone on my
network I can just use their username as an email
address. Evolution doen't consider this to be a
valid address (perhaps because there's no '@' in
it?). This forces me to type the full domain name
you see in my email address (shudder!) for every
recipient I specify (which could easily be 10s of
people).

Steps to reproduce the problem:
1. try to send email to 'feleus' 
2. evolution complains
3. I have to type in the complete address

Actual Results:
typing frenzy could occur :-)

Expected Results:
it should just accept this like every other email
client I've seen or used (kmail, balsa, xc-mail,
pine, mutt, elm, netscape)

How often does this happen? 
always

Additional Information:
some mail clients have a sort of 'default domain'
which gets appended in these cases. That would
solve the problem. (NOTE: I'm using IMAP because
of another problem which I'll send another bug
report/feature request about. And I'm running
RH7.2, not 7.1, but is isn't in the list.)
