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. -- Cheers, Jeremy -- ## List details at https://lists.exim.org/mailman/listinfo/exim-users ## Exim details at http://www.exim.org/ ## Please use the Wiki with this list - http://wiki.exim.org/
