empty payload when receiving HTML mails with image in body and a attachment MULE - mule-esb

Question

I'm using imap connector its working fine in all the scenarios but when an email sent with an image in the body and an attachment I'm getting empty payload from the imap listener.
if I send an email with an image in the body and no attachment the image is saving as separate file and content in the body as a separate file that's okay.
Did anyone faced the same issue or can anyone please provide a fix?
even tried disableTransportTransformer="true in imap connector its not working

email body should be extracted through

Answer 1

The image is likely another attachement, not the body. Try to iterate over the attachements and log information about the message to confirm it:
<foreach collection="#[message.inboundAttachments]" doc:name="ForEach">
<logger />
</foreach>
