Zip an Email's Attachments into One File

Demonstrates the Chilkat Email.ZipAttachments method, which replaces all of an email's attachments with a single Zip file attachment having the specified filename. The original attachments are removed and packed into the Zip. This example adds two attachments and zips them into one.

Background: Bundling multiple attachments into a single .zip keeps a message tidy, compresses the payload, and works around recipients or gateways that limit the number of attachments. Note that the filename here (files.zip) names the attachment inside the message — it is not a path on disk. The reverse operation is UnzipAttachments.
