mail rule + applescript. auto attachment download and rename file.

Hello there!

I want to automatically download any attachments that arive from a specific email sender to a specific email account of mine. these may be .doc or .xls or .pdf files. I want the attachments to be saved in a folder on my desktop, but renamed as follows: "dd/mm/yyyy - original attachment name"

{dd/mm/yyyy refers to the day/month/year the email arrived, then a "(space)-(space)", and then the original filename of the attachment}

I understand this requires a combination of a mail rule to select the specific email sender, but then I need an applescript in order to do the downloading/renaming process. Can someone please provide me with a complete script for that. I would deeply appreciate it. I found downloading scripts, but none with renaming in a specific format as mine, in order to customize it according to my needs. I am not fluent in script-language so please slightly explain the steps along.

Thank you!
