[Evolution] language selection in composer

[Gerhard Schuck <pc01188 srv cc hit-u ac jp>]

If I reply to a mail the one-liner above the cited mail is in German,
but I would like to have it in English. Is there a way to configure this
without changing my whole desktop from German to English?

I use Evolution 2.4.1 on Ubuntu Breezy.

Thanks in advance for any hint.
