private static void cleanAttachments(MimeMessage message) { try { if (message.getContent() != null) { MimeMultipart multi = (MimeMultipart) message.getContent(); for (int j = 0; j < multi.getCount(); j++) { BodyPart bodyPart = multi.getBodyPart(j); if (bodyPart.getDataHandler().getDataSource() instanceof FileDataSource) { FileDataSource f = (FileDataSource) bodyPart.getDataHandler().getDataSource(); f.getFile().delete(); } } } } catch (MessagingException e) { e.printStackTrace(); } catch (IOException e) { e.printStackTrace(); } }

For when you use File.createTempFile  to support the attachments of a mail message and cannot use deleteOnExit because the JVM will not exit.

Something i saw myself needing.

All the best.
