Support has recently been added in the Exim development tree for UTF-8 in email envelopes. It has not hit a released Exim version yet.
For the technical, this is the SMTPUTF8 extension defined in RFC 6530 et. al. Details are in the experimental.txt documentation. People interested in trying this in a production environment will need to compile from source, with EXPERIMENTAL_INTERNATIONAL defined. Feedback would be very welcome as the systems I can run it on are unlikely to see much internationalized traffic. The Exim sources are available from git://git.exim.org/exim.git The bug for SMTPUTF8 specifically is http://bugs.exim.org/show_bug.cgi?id=1516 and the umbrella bug for internationalization is http://bugs.exim.org/show_bug.cgi?id=1177 -- 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/
