How do I map attachments submitted via mailhandler? In Drupal-7 I'm reading an imap mailbox with mailhandler. I have the mapping setup via feeds. This processes text messages creating a node but messages with attachments don't have the attachments stored. 

How do I store the attachments?
I created a file field and mapped the attachment. 


Create the file field under structure/types. Set number of values to 'unlimited'. 
Under the feeds mapping map attachments to File:URI
