Get the Total Size of an IMAP Message

Demonstrates the Chilkat Imap.GetMailSize method, which returns the complete server-reported size of a message in bytes, including attachment data. The only argument is the Email. This example fetches only the headers and prints the full message size.

Background: The server reports each message's total size, so this value is available even when only the headers were downloaded. That lets a client show a size column in a message list, sort by size, or warn the user before downloading an unusually large message — all without fetching the full body first.
