[Evolution] Domain auto-completion in 'To:' field

[Erik Williamson <erik cpsc ucalgary ca>]

Hi there, 

I'm just wondering if anyone knows of a configuration option whereby I
don't have to enter the whole domain name in the 'To:' field: So if I
just enter a username, evolution will assume that it should append a
pre-defined '@somedomain.com'.

Thanks for such an amazing product!
Erik.
