Save All Email Attachments to a Directory

Demonstrates the Chilkat Email.SaveAllAttachments method, which saves all of the email's attachments to a directory. If the directory or any of its components do not exist, Chilkat creates them automatically. This example adds two attachments and saves them.

Background: Each attachment is written using its own filename. Because those filenames come from the sender and may collide, consider the OverwriteExisting property (which can auto-generate unique names) and RemoveAttachmentPaths (which strips embedded path info) to keep saved files safe and non-clobbering — important when processing untrusted incoming mail.
