Pascal (Lazarus/Delphi)

Fetch an IMAP Message as MIME Text

Demonstrates the Chilkat Imap.FetchSingleAsMime method, which downloads one message and returns its MIME source as a string. If the second argument (bUid) is true, the first argument is a UID; otherwise it is a sequence number. This example fetches message 1's raw MIME.

Background: Sometimes you want the message exactly as it exists on the server — the raw MIME — rather than a parsed Email object. That is what you save to a .eml file, feed to another parser, or archive verbatim. This method returns the MIME as text; for messages that may contain binary data, the BinData variant FetchSingleBd preserves the exact bytes.
