How come gmail is showing 'noname' attachments for images attached using MimeMessageHelper addInline sent with Amazon SES?
Question
When using Spring MimeMessageHelper to attach the icons using addInLine and sending with SES, some of the icons appear as 'noname' attachments. These images seem to be random unused images from the same folder.
AddInLine code
private void attachIconsInEmailBody(MimeMessageHelper messageHelper, String iconsPath) throws IOException, MessagingException {
Resource[] resources = resourcePatternResolver.getResources("classpath:" + iconsPath + "*.*");
for (Resource attRes: resources) {
String iconName = attRes.getFilename();
messageHelper.addInline(iconName.split("\\.")[0], attRes);
}
Email code
MimeMessage message = new MimeMessage(session);
MimeMessageHelper messageHelper = new MimeMessageHelper(message, true, "UTF-8");
messageHelper.setFrom(new InternetAddress(emailObject.getSender()));
messageHelper.setTo(InternetAddress.parse(emailObject.getRecipients()));
messageHelper.setSubject(emailObject.getSubject());
messageHelper.setText(htmlBody, true);
messageHelper.setSentDate(new Date(System.currentTimeMillis()));
// add all the icons in-line to display in the email body
attachIconsInEmailBody(messageHelper,"static/logo/SG/");
Sendmail code:
// send the email using the sendRawEmail API
ByteArrayOutputStream outputStream = new ByteArrayOutputStream();
message.writeTo(outputStream);
RawMessage rawMessage = new RawMessage(ByteBuffer.wrap(outputStream.toByteArray()));
SendRawEmailRequest rawEmailRequest = new SendRawEmailRequest(rawMessage);
SendRawEmailResult emailResult = sesClient.sendRawEmail(rawEmailRequest);
// set the response back in the email object for any further recon
emailObject.setEmailResult(emailResult);
outputStream.close();
return emailResult;

I know it's a bit late to answer this question. I recently also experienced this issue while sending email using AWS SES. The reason is that the MimeMessageHelper does not set the filename for our inline images when it creates BodyPart from our images. The contentId it uses is twisted a bit with the prefix < and suffix > . We may retrieve the corresponding BodyPart instance from the helper class by the following code:
private void attachIconsInEmailBody(MimeMessageHelper messageHelper, String iconsPath) throws IOException, MessagingException {
Resource[] resources = resourcePatternResolver.getResources("classpath:" + iconsPath + "*.*");
for (Resource attRes: resources) {
String iconName = attRes.getFilename();
String contentId = iconName.split("\\.")[0];
messageHelper.addInline(contentId , attRes);
messageHelper.getMimeMultipart().getBodyPart("<" + contentId + ">").setFileName(iconName);
}
