Other mail programs like Pine and Eudora allow
their users to specify a default domain to add to
the end of a "To:" address that doesn't contain an
@somewhere.com.  It would be great if Evolution
had such an option.

I'm a university student, and most of the email I
send goes to another address within the
stanford.edu domain.  I'd love to be able to type
"jsmith" in the "To:" line and have Evolution
automatically convert that to
"jsmith@stanford.edu" when sending (perhaps with
an optional popup showing the conversion).  It
seems that many people would benefit from this
feature.
