Good day. New member here

Long story short:
I would like a script that grabs the attachments from a incoming mails and saves them in a specified folder with the subject as the filename.

The bigger picture:
I regularly recieve mails with attached pdf files. The pdf filename is always called "Vedlegg" ("attachement" in norwegian) and the subject field is always "ARBEIDSORDRE 589492/2012 ,VH35682 ,FORHÅNDSVIS" except for the numbers being different each time. I work in a car workshop and these pdf's are work-orders containing a description of what to repair on the different cars. Thus the numbers will be different on each mail, but I want them to be automatically stored with the subject field as the filename.

Also, I am aware that "/" can not be used in filenames. So I would like something that inserts a space instead and also maybe deletes the first and last word "ARBEIDSORDRE" and "FORHÅNDSVIS" as those are of no interest when I later want to search for it.

I have fund and tried several scripts that did similar to this, but none that does it excactly the way I'd want to.

Kind Regards
