Pascal (Lazarus/Delphi)

Load MIME from a File

Demonstrates the Chilkat Mime.LoadMimeFile method, which reads and parses a MIME entity from a local file. The only argument is the file path.

Note: The file paths are relative to the application's current working directory. Absolute paths may also be used. Supply the paths appropriate to your own environment.

Background: This is the usual entry point when a message is on disk — an .eml file, a saved attachment, an exported MIME container. It reads and parses in one call, replacing the current object on success. If the file cannot be opened the object is left unchanged, so a failed load never corrupts existing state.
