When an user uses the "Send an email... as attachment" function on a Zip file, the attachment is suffixed with ".dat" (instead of having the 'test.zip' attachment, user has 'test.zip.dat' attachment)
The recipient can not then open the zip file. He has to download the attachment, then suppress the .dat extension.
The document in ICN has the following retrieval name : test.zip
The document in ICN has the following mime type : application/x-zip
Did I miss something in my configuration? Function works with PDF, TIFF, Office documents, and other various mime types I tested.
