SMTPUTF8 is enabled.
so there is dns servers with domains in utf8 existing ?
all my known dns servers uses idn, not eai, postfix imho need to convert
eai to idn dns to know if domain exists on dns
to block domainnames in utf8 it would only work in spamassassin or
rspamd, so i keep smtputf8 in postfix disabled still, unicode came to
late with it, that will hopefully stay at idn not eai encodeing if eai
come on dns it will in princible be possible to make look alike domains
owned by 2 diffrent registrants :/
if dns servers is not carefully make it impossible
