Sender "Mail" adapter - CSV file attachment

Hi there

I'm looking for some help in configuring a sender mail adapter that receives ".csv" files. I did read some blogs that mention using the "PayloadSwapBean" module to read the mail attachment instead of the mail content. My problem is to now convert the ".csv" file into a message. Is there a module that I can use ( is it the "MessageTransfomBean" ) and how. Any help would be appreciated.

Thanks
