Eudora (used to) automatically save attachments to emails in a separate directory, i.e. the mime-encoded attachments in emails were removed from the email and the file decoded and stored in the directory on the file system.

This is all when and good but people ended up with a lot of old attachments filling up their home directories even thought the original emails had been deleted.

This script examines emails and attachments and deletes any attachments that do not have a corresponding email.

This is one of my very first python scripts - one of my first scripts even. BACK UP YOUR FILES. I AM AN IDIOT AND ALL MY CODE IS DANGEROUS
