/* When it is not possible to resolve the e-mail address of
       destination server (MX record) eventually because the domain is
       invalid, this class tries to resolve the domain address (A
       record). If it fails, usually the resolver library assumes that
       could be because the specified domain is just the subdomain
       part. So, it appends the local default domain and tries to
       resolve the resulting domain. It may happen that the local DNS
       has an * for the A record, so any sub-domain is resolved to some
       local IP address. This prevents the class from figuring if the
       specified e-mail address domain is valid. To avoid this problem,
       just specify in this variable the local address that the
       resolver library would return with gethostbyname() function for
       invalid global domains that would be confused with valid local
       domains. Here it can be either the domain name or its IP address. */
