Springboot: sending an email with attachment

Question

I have this piece of code to send emails in SpringBoot, that is working fine, but I have this error:

Failed messages: javax.mail.MessagingException: IOException while sending message;
  nested exception is:
    javax.net.ssl.SSLException: java.net.SocketException: Broken pipe (Write failed)

when I send big files, like 88MB

 public void sendMailWithAttachment(String to, String subject, String body, String fileToAttach) {

        MimeMessagePreparator preparator = mimeMessage -> {

            MimeMessageHelper message = new MimeMessageHelper(mimeMessage, true, "UTF-8");
            message.setTo(to);
            message.setFrom(new InternetAddress("[email protected]"));
            message.setSubject(subject);
            message.setText(body);
            FileSystemResource file = new FileSystemResource(new File(fileToAttach));
            message.addAttachment("logo.jpg", file);
        };

        try {
            javaMailSender.send(preparator);
        }
        catch (Exception ex) {
            // simply log it and go on...
            System.err.println(ex.getMessage());
        }
    }
