For example, "" should be encoded "" by Punycode. This issue will be closed soon.

`src/smtpd/smtpd_check.c` on Postfix 3.1.4 ```c static int reject_unknown_client(SMTPD_STATE *state) { const char *myname = "reject_unknown_client"; if (msg_verbose) msg_info("%s: %s %s", myname, state->name, state->addr); /* RFC 7372: Email Authentication Status Codes....

We need a sample email including the status code.
