Receive mail with PDF attachment into XI and send to ABAP proxy

Hi,

I have a scenario where I need to receive a mail into XI that has a PDF attachment. This attachment needs to be retained as ultimately I need to send the message into CRM via an ABAP proxy and read the attachment and load against a business partner.

However, as I am only on SP13 I do not have the parameters such "Keep Attachments" available to use.

So I have two questions:

1. How do I receive the mail into XI with the PDF attachment ?

2. How do I read the attachment in an ABAP proxy ?

Any guidance in either question would be appreciated.

Cheers

Colin.
