                     Map inlines) throws Exception{
        MimeMessage mimeMessage = mailSender.createMimeMessage();
        MimeMessageHelper helper = new MimeMessageHelper(mimeMessage, true);
        helper.setFrom(from);
        helper.setTo(toMails);
        helper.setSubject(subject);
        helper.setText(text, true); //支持html

        // 增加inline
        if(inlines != null){
            for(Map.Entry entry: inlines.entrySet()){
                if(entry.getValue() instanceof ClassPathResource){
                    helper.addInline(entry.getKey(), (Resource) entry.getValue());
                }

            }

错误码554

554 DT:SPM 发送的邮件内容包含了未被许可的信息,或被系统识别为垃圾邮件。请检查是否有用户发送病毒或者垃圾邮件;

被网易邮箱识别为垃圾邮件了,有个歪招,就是把发送邮箱添加到cc里头

        helper.setCc(from);
