Ouch. If memory serves, this is my tiny contribution to exim.

The simple-minded fix:

  if (strchr(s.nodename, '.') == NULL)
    {
    struct hostent *host = gethostbyname(s.nodename);
    if (host)
      primary_hostname = string_copy((char *)host->h_name);
    else
      primary_hostname = string_copy(s.nodename);
    }
  else primary_hostname = string_copy(s.nodename);
