If you use greek, cyrillic or any other non [a-z] letter , you will fail to send mail, as all non [a-z] domainnames must be encoded in punycode: Example: xn--strae-oqa.de <-> straße.de if you use straße.de directly in smtp, you will get a nice "relay denied" if your lucky, but most likely a "550 Restricted characters in address" deny message = Restricted characters in address domains = +local_domains local_parts = ^[.] : ^.*[\$@%!/|] : ^.*x24 : ^.*0.44 deny message = Restricted characters in address domains = !+local_domains local_parts = ^[./|] : ^.*[\$@%!] : ^.*/\\.\\./ : ^.*x24 : ^.*0.44 (if anyone does not have those rules, you are highly encouraged to add those) best regards, Marius -- ## 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/
