JavaMail:"域包含字符串中的控件或空格"错误消息,因为域有丹麦字符

Question

现在允许使用具有特殊丹麦字符的域,例如æøå,但我不能强制java邮件接受此.

    @Test()
public void testMailAddressWithDanishCharacters1() throws AddressException, UnsupportedEncodingException {
    InternetAddress cAddress = new InternetAddress( "test@testæxample12345123.com", null, "utf-8" );
    System.out.println( cAddress.toString() );
    cAddress.validate();
}

@Test()
public void testMailAddressWithDanishCharacters2() throws AddressException, UnsupportedEncodingException {
    InternetAddress cAddress = new InternetAddress( "test@testæxample12345123.com", false );
    System.out.println( cAddress.toString() );
    cAddress.validate();
}

@Test()
public void testMailAddressWithDanishCharacters3() throws AddressException, UnsupportedEncodingException {
    InternetAddress cAddress = new InternetAddress( "test@testæxample12345123.com", true );
    System.out.println( cAddress.toString() );
    cAddress.validate();
}

所有测试都在InternetAddress的构造函数或validate()方法中失败.如何在域中处理这些特殊的丹麦字符.我敢打赌其他国家/地区的域名与电子邮件在javamail InternetAddress中存在同样的问题.

Java Mail 不支持 i18n 域名，因此您必须使用标准规则来使用IDNA 规则对其进行转义。
