  Actually chkuser handles xn-- domains, but in the wrong way (it does 
not consider more levels of xn-- names, like xn-subdomain.xn--domain.com).

To eliminate any problem, with current version, installations should be 
modified in this way:

Or disable/comment in chkuser_settings.h
     #define CHKUSER_RCPT_FORMAT
     #define CHKUSER_SENDER_FORMAT

or delete/comment within chkuser.c two separates occurrences of
         if (strncmp (domain->s, "xn--", 4) == 0) {
                 if (strstr (&domain->s[4], "--") != NULL)
                         return 0;
         } else {
                 if (strstr (domain->s, "--") != NULL)
                         return 0;
         }


Recompile after change.

Regards,

Tonino
