Dear list, sorry for my previous incomplete message.
I'm trying to setup a postfix 3.0 with a mysql backend to host utf8 domains. The setup is almost ready but when I make some tests, utf8 domains are not found (I see "relay access denied" errors in the logs) and I get the same result using postmap:
postmap -q raté.com mysql:/etc/postfix/sql-domains.cf
If I try with a domain containing ascii characters only, it works just fine. What am I doing wrong ? Thanks for your help, Antoine Nguyen
