i want to make a filter that will send messages with *.ods,*.pdf and *.jpg files in the attachments to move to a folder and make it with a label blue for ods red for pdf and green for jpg i use these extentions every day by many diferent people but i want them to sort by file extention and not by sender because the same sender will send me an .ods and then right after send me a pdf or jpg the pdf/jpg goes to the customer and the ods gets filed for storage. after reading a few articles on filters it was thunderbirds body filter loots at header body and attachments but i cant seem to get my filer to work and some documentation im using imap not pop

i have tried creating a custome header named Content-Type contains application/vnd.oasis.opendocument.spreadsheet and tried contains .ods did the same for pdf files nothing but if some one included .ods in the text of the message the filter worked
