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
