I am using a Receiver Email Communication Channel. I need to be able to send emails to dynamically assigned recipients. I know I need to use the 'Use Mail Package' option. I am doing this and it is working. However, I also need to attatch the payload to the email. This will work by not specifying the 'Use Mail Package' option. I need to do both.
I can send an email with an attatchment. But the content of this attachment has been generated by a Message Mapping. I want the payload on the attchment.
