Describe the bug
When querying an IDN domain with utf-8 characters in them, the connection gets closed prematurely and an error gets logged.
To Reproduce
Steps to reproduce the behavior:
Run a lookup with a domain that has an utf-8 character in it: /usr/sbin/postmap -q ätsch.de socketmap:inet:127.0.0.1:8461:postfix
Expected behavior
The domain should be converted to it's ascii counterpart (in this example xn--tsch-koa.de) and resolved correctly.
