I relented and added a punycode version of the domain name to my MySQL tables. Also registered (mje@) 'pösix.eu' for proper testing purposes with e-mail. Phil: What exactly do you have 'allow_utf8_domains' and 'dns_check_names_pattern' set to and exactly where should they be included in the config file. I'm running exim-4.77 (Gentoo). Just like to get it right first time around. Are there mail clients (MUA) which translate between UTF-8 and PunyCode or is this the job of the MTA to try and sort out? Thunderbird and Evolution both fail with a similar It would probably be useful if exim could at least 'translate' puny to UTF in the final deliver stage (eg: deliver by mysql) - but I might be able to fudge that by having both versions of the name in my DB table - ie end up with e-mail delivered to my exim via punycode being appropriately placed in the correct UTF directory with UTF headers. Some native UTF-8/Punycode would be preferred though. -- . . ___. .__ Posix Systems - (South) Africa /| /| / /__ [email protected] - Mark J Elkins, Cisco CCIE / |/ |ARK \_/ /__ LKINS Tel: +27 12 807 0590 Cell: +27 82 601 0496
