Exim doesn't care much (unless you tell it specially).

You might be interested in the internationalisation support,

http://exim.org/exim-html-current/doc/html/spec_html/ch-internationalisation.html

... though I don't know whether the Debian build includes that
(run "exim -bV", find the "Support for" line and look for I18N)
nor whether your next hop does.
