Compute a Global Unique Key for an Email

See more Email Object Examples

Demonstrates the Chilkat Email.ComputeGlobalKey2 method, which computes a global unique key for the email — an MD5 digest formed from the message-id concatenated with other identifying fields. The first argument is the encoding of the returned key (such as hex or base64), and the second folds the key when true. This example loads an email and computes its key as hex.
