Sender mail adapter sending xml attachment comes with .bin
I have the following scenario: Sender Mail >> RFC
As I can receive multiples attachments I´m using payload swap bean and adapter module to get all attachments together in the first attachment.
In most cases is working very well, but in some cases the xml attachment is coming as a ".bin".
The same mail with this wrong format, when it´s been forwarded, comes with the right xml file so I can figure that is the mail format sent by vendor.
I tried to simulate this error myself and I could observe that when I change the message format from html to plain text in my outlook I get the same error, the attachments comes as .bin
Does anyone know how can I receive those mails in the right format?
Thanks for your help!
