Sender Mail Adapter with SAP Conversion agent

have some1 used SAP conversion agent on attchment from XI Sender Mail adapter?

it seems to ignore the attchment of the e-mail

the sender configuration module tab is as follows :

1.localejbs/AF_Modules/PayloadSwapBean transform

2.localejbs/sap.com/com.sap.nw.cm.xi/CMTransformBean CM

3.sap.com/com.sap.aii.adapter.mail.app/XIMailAdapterBean mail

The paramters are

transform swap.keyName Content-Disposition

transform swap.keyName Content-Description

transform swap.keyValue attachment

transform swap.keyValue codeco

CM TransformationName ZIM_CODECO_VALIDATIONS

The Convesion Agnet runs prefectly when using the Conversion Agent engine
